-
-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

- * Psbt class can parse and generate a PSBT binary based off of the BIP174.
- * There are 6 roles that this class fulfills. (Explained in BIP174)
- *
- * Creator: This can be done with `new Psbt()`
- * Updater: This can be done with `psbt.addInput(input)`, `psbt.addInputs(inputs)`,
- *   `psbt.addOutput(output)`, `psbt.addOutputs(outputs)` when you are looking to
- *   add new inputs and outputs to the PSBT, and `psbt.updateGlobal(itemObject)`,
- *   `psbt.updateInput(itemObject)`, `psbt.updateOutput(itemObject)`
- *   addInput requires hash: Buffer | string; and index: number; as attributes
- *   and can also include any attributes that are used in updateInput method.
- *   addOutput requires script: Buffer; and value: number; and likewise can include
- *   data for updateOutput.
- *   For a list of what attributes should be what types. Check the bip174 library.
- *   Also, check the integration tests for some examples of usage.
- * Signer: There are a few methods. signAllInputs and signAllInputsAsync, which will search all input
- *   information for your pubkey or pubkeyhash, and only sign inputs where it finds
- *   your info. Or you can explicitly sign a specific input with signInput and
- *   signInputAsync. For the async methods you can create a SignerAsync object
- *   and use something like a hardware wallet to sign with. (You must implement this)
- * Combiner: psbts can be combined easily with `psbt.combine(psbt2, psbt3, psbt4 ...)`
- *   the psbt calling combine will always have precedence when a conflict occurs.
- *   Combine checks if the internal bitcoin transaction is the same, so be sure that
- *   all sequences, version, locktime, etc. are the same before combining.
- * Input Finalizer: This role is fairly important. Not only does it need to construct
- *   the input scriptSigs and witnesses, but it SHOULD verify the signatures etc.
- *   Before running `psbt.finalizeAllInputs()` please run `psbt.validateSignaturesOfAllInputs()`
- *   Running any finalize method will delete any data in the input(s) that are no longer
- *   needed due to the finalized scripts containing the information.
- * Transaction Extractor: This role will perform some checks before returning a
- *   Transaction object. Such as fee rate not being larger than maximumFeeRate etc.

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+ * Psbt class can parse and generate a PSBT binary based off of the BIP174.
+ * There are 6 roles that this class fulfills. (Explained in BIP174)
+ *
+ * Creator: This can be done with `new Psbt()`
+ * Updater: This can be done with `psbt.addInput(input)`, `psbt.addInputs(inputs)`,
+ *   `psbt.addOutput(output)`, `psbt.addOutputs(outputs)` when you are looking to
+ *   add new inputs and outputs to the PSBT, and `psbt.updateGlobal(itemObject)`,
+ *   `psbt.updateInput(itemObject)`, `psbt.updateOutput(itemObject)`
+ *   addInput requires hash: Buffer | string; and index: number; as attributes
+ *   and can also include any attributes that are used in updateInput method.
+ *   addOutput requires script: Buffer; and value: number; and likewise can include
+ *   data for updateOutput.
+ *   For a list of what attributes should be what types. Check the bip174 library.
+ *   Also, check the integration tests for some examples of usage.
+ * Signer: There are a few methods. signAllInputs and signAllInputsAsync, which will search all input
+ *   information for your pubkey or pubkeyhash, and only sign inputs where it finds
+ *   your info. Or you can explicitly sign a specific input with signInput and
+ *   signInputAsync. For the async methods you can create a SignerAsync object
+ *   and use something like a hardware wallet to sign with. (You must implement this)
+ * Combiner: psbts can be combined easily with `psbt.combine(psbt2, psbt3, psbt4 ...)`
+ *   the psbt calling combine will always have precedence when a conflict occurs.
+ *   Combine checks if the internal bitcoin transaction is the same, so be sure that
+ *   all sequences, version, locktime, etc. are the same before combining.
+ * Input Finalizer: This role is fairly important. Not only does it need to construct
+ *   the input scriptSigs and witnesses, but it SHOULD verify the signatures etc.
+ *   Before running `psbt.finalizeAllInputs()` please run `psbt.validateSignaturesOfAllInputs()`
+ *   Running any finalize method will delete any data in the input(s) that are no longer
+ *   needed due to the finalized scripts containing the information.
+ * Transaction Extractor: This role will perform some checks before returning a
+ *   Transaction object. Such as fee rate not being larger than maximumFeeRate etc.

+/**
+ * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
+ * tasks are specified as parameters to the function, after the usual callback
+ * parameter, with the parameter names matching the names of the tasks it
+ * depends on. This can provide even more readable task graphs which can be
+ * easier to maintain.
+ *
+ * If a final callback is specified, the task results are similarly injected,
+ * specified as named parameters after the initial error parameter.
+ *
+ * The autoInject function is purely syntactic sugar and its semantics are
+ * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
+ *
+ * @name autoInject
+ * @static
+ * @memberOf module:ControlFlow
+ * @method
+ * @see [async.auto]{@link module:ControlFlow.auto}
+ * @category Control Flow
+ * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
+ * the form 'func([dependencies...], callback). The object's key of a property
+ * serves as the name of the task defined by that property, i.e. can be used
+ * when specifying requirements for other tasks.
+ * * The `callback` parameter is a `callback(err, result)` which must be called
+ *   when finished, passing an `error` (which can be `null`) and the result of
+ *   the function's execution. The remaining parameters name other tasks on
+ *   which the task is dependent, and the results from those tasks are the
+ *   arguments of those parameters.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback, and a `results` object with any completed
+ * task results, similar to `auto`.
+ * @returns {Promise} a promise, if no callback is passed
+ * @example
+ *
+ * //  The example from `auto` can be rewritten as follows:
+ * async.autoInject({
+ *     get_data: function(callback) {
+ *         // async code to get some data
+ *         callback(null, 'data', 'converted to array');
+ *     },
+ *     make_folder: function(callback) {
+ *         // async code to create a directory to store a file in
+ *         // this is run at the same time as getting the data
+ *         callback(null, 'folder');
+ *     },
+ *     write_file: function(get_data, make_folder, callback) {
+ *         // once there is some data and the directory exists,
+ *         // write the data to a file in the directory
+ *         callback(null, 'filename');
+ *     },
+ *     email_link: function(write_file, callback) {
+ *         // once the file is written let's email a link to it...
+ *         // write_file contains the filename returned by write_file.
+ *         callback(null, {'file':write_file, 'email':'user@example.com'});
+ *     }
+ * }, function(err, results) {
+ *     console.log('err = ', err);
+ *     console.log('email_link = ', results.email_link);
+ * });
+ *
+ * // If you are using a JS minifier that mangles parameter names, `autoInject`
+ * // will not work with plain functions, since the parameter names will be
+ * // collapsed to a single letter identifier.  To work around this, you can
+ * // explicitly specify the names of the parameters your task function needs
+ * // in an array, similar to Angular.js dependency injection.
+ *
+ * // This still has an advantage over plain `auto`, since the results a task
+ * // depends on are still spread into arguments.
+ * async.autoInject({
+ *     //...
+ *     write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {
+ *         callback(null, 'filename');
+ *     }],
+ *     email_link: ['write_file', function(write_file, callback) {
+ *         callback(null, {'file':write_file, 'email':'user@example.com'});
+ *     }]
+ *     //...
+ * }, function(err, results) {
+ *     console.log('err = ', err);
+ *     console.log('email_link = ', results.email_link);

+ * @property {Function} running - a function returning the number of items
+ * currently being processed. Invoke with `queue.running()`.
+ * @property {Function} workersList - a function returning the array of items
+ * currently being processed. Invoke with `queue.workersList()`.
+ * @property {Function} idle - a function returning false if there are items
+ * waiting or being processed, or true if not. Invoke with `queue.idle()`.
+ * @property {number} concurrency - an integer for determining how many `worker`
+ * functions should be run in parallel. This property can be changed after a
+ * `queue` is created to alter the concurrency on-the-fly.
+ * @property {number} payload - an integer that specifies how many items are
+ * passed to the worker function at a time. only applies if this is a
+ * [cargo]{@link module:ControlFlow.cargo} object
+ * @property {AsyncFunction} push - add a new task to the `queue`. Calls `callback`
+ * once the `worker` has finished processing the task. Instead of a single task,
+ * a `tasks` array can be submitted. The respective callback is used for every
+ * task in the list. Invoke with `queue.push(task, [callback])`,
+ * @property {AsyncFunction} unshift - add a new task to the front of the `queue`.
+ * Invoke with `queue.unshift(task, [callback])`.
+ * @property {AsyncFunction} pushAsync - the same as `q.push`, except this returns
+ * a promise that rejects if an error occurs.
+ * @property {AsyncFunction} unshirtAsync - the same as `q.unshift`, except this returns
+ * a promise that rejects if an error occurs.
+ * @property {Function} remove - remove items from the queue that match a test
+ * function.  The test function will be passed an object with a `data` property,
+ * and a `priority` property, if this is a
+ * [priorityQueue]{@link module:ControlFlow.priorityQueue} object.
+ * Invoked with `queue.remove(testFn)`, where `testFn` is of the form
+ * `function ({data, priority}) {}` and returns a Boolean.
+ * @property {Function} saturated - a function that sets a callback that is
+ * called when the number of running workers hits the `concurrency` limit, and
+ * further tasks will be queued.  If the callback is omitted, `q.saturated()`
+ * returns a promise for the next occurrence.
+ * @property {Function} unsaturated - a function that sets a callback that is
+ * called when the number of running workers is less than the `concurrency` &
+ * `buffer` limits, and further tasks will not be queued. If the callback is
+ * omitted, `q.unsaturated()` returns a promise for the next occurrence.
+ * @property {number} buffer - A minimum threshold buffer in order to say that
+ * the `queue` is `unsaturated`.
+ * @property {Function} empty - a function that sets a callback that is called
+ * when the last item from the `queue` is given to a `worker`. If the callback
+ * is omitted, `q.empty()` returns a promise for the next occurrence.
+ * @property {Function} drain - a function that sets a callback that is called
+ * when the last item from the `queue` has returned from the `worker`. If the
+ * callback is omitted, `q.drain()` returns a promise for the next occurrence.
+ * @property {Function} error - a function that sets a callback that is called
+ * when a task errors. Has the signature `function(error, task)`. If the
+ * callback is omitted, `error()` returns a promise that rejects on the next
+ * error.
+ * @property {boolean} paused - a boolean for determining whether the queue is
+ * in a paused state.
+ * @property {Function} pause - a function that pauses the processing of tasks
+ * until `resume()` is called. Invoke with `queue.pause()`.
+ * @property {Function} resume - a function that resumes the processing of
+ * queued tasks when the queue is paused. Invoke with `queue.resume()`.
+ * @property {Function} kill - a function that removes the `drain` callback and
+ * empties remaining tasks from the queue forcing it to go idle. No more tasks
+ * should be pushed to the queue after calling this function. Invoke with `queue.kill()`.
+ *
+ * @example
+ * const q = aync.queue(worker, 2)

+ * An "async function" in the context of Async is an asynchronous function with
+ * a variable number of parameters, with the final parameter being a callback.
+ * (`function (arg1, arg2, ..., callback) {}`)
+ * The final callback is of the form `callback(err, results...)`, which must be
+ * called once the function is completed.  The callback should be called with a
+ * Error as its first argument to signal that an error occurred.
+ * Otherwise, if no error occurred, it should be called with `null` as the first
+ * argument, and any additional `result` arguments that may apply, to signal
+ * successful completion.
+ * The callback must be called exactly once, ideally on a later tick of the
+ * JavaScript event loop.
+ *
+ * This type of function is also referred to as a "Node-style async function",
+ * or a "continuation passing-style function" (CPS). Most of the methods of this
+ * library are themselves CPS/Node-style async functions, or functions that
+ * return CPS/Node-style async functions.
+ *
+ * Wherever we accept a Node-style async function, we also directly accept an
+ * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
+ * In this case, the `async` function will not be passed a final callback
+ * argument, and any thrown error will be used as the `err` argument of the
+ * implicit callback, and the return value will be used as the `result` value.
+ * (i.e. a `rejected` of the returned Promise becomes the `err` callback
+ * argument, and a `resolved` value becomes the `result`.)
+ *
+ * Note, due to JavaScript limitations, we can only detect native `async`
+ * functions and not transpilied implementations.
+ * Your environment must have `async`/`await` support for this to work.
+ * (e.g. Node > v7.6, or a recent version of a modern browser).
+ * If you are using `async` functions through a transpiler (e.g. Babel), you
+ * must still wrap the function with [asyncify]{@link module:Utils.asyncify},
+ * because the `async function` will be compiled to an ordinary function that
+ * returns a promise.

- * Decoders transform json objects with unknown structure into known and

- * primitive decoder functions, such as `boolean()` and `string()`, or by
- * applying higher-order decoders to the primitives, such as `array(boolean())`
- * or `dict(string())`.
- *
- * Each of the decoder functions are available both as a static method on
- * `Decoder` and as a function alias -- for example the string decoder is
- * defined at `Decoder.string()`, but is also aliased to `string()`. Using the
- * function aliases exported with the library is recommended.
- *
- * `Decoder` exposes a number of 'run' methods, which all decode json in the
- * same way, but communicate success and failure in different ways. The `map`
- * and `andThen` methods modify decoders without having to call a 'run' method.
- *
- * Alternatively, the main decoder `run()` method returns an object of type
- * `Result<A, DecoderError>`. This library provides a number of helper
- * functions for dealing with the `Result` type, so you can do all the same
- * things with a `Result` as with the decoder methods.

- * Updater: This can be done with `psbt.addInput(input)`, `psbt.addInputs(inputs)`,
- *   `psbt.addOutput(output)`, `psbt.addOutputs(outputs)` when you are looking to
- *   add new inputs and outputs to the PSBT, and `psbt.updateGlobal(itemObject)`,
- *   `psbt.updateInput(itemObject)`, `psbt.updateOutput(itemObject)`
- *   addInput requires hash: Buffer | string; and index: number; as attributes
- *   and can also include any attributes that are used in updateInput method.
- *   addOutput requires script: Buffer; and value: number; and likewise can include
- *   data for updateOutput.
- *   For a list of what attributes should be what types. Check the bip174 library.
- *   Also, check the integration tests for some examples of usage.
- * Signer: There are a few methods. signAllInputs and signAllInputsAsync, which will search all input
- *   information for your pubkey or pubkeyhash, and only sign inputs where it finds
- *   your info. Or you can explicitly sign a specific input with signInput and
- *   signInputAsync. For the async methods you can create a SignerAsync object
- *   and use something like a hardware wallet to sign with. (You must implement this)
- * Combiner: psbts can be combined easily with `psbt.combine(psbt2, psbt3, psbt4 ...)`
- *   the psbt calling combine will always have precedence when a conflict occurs.
- *   Combine checks if the internal bitcoin transaction is the same, so be sure that
- *   all sequences, version, locktime, etc. are the same before combining.
- * Input Finalizer: This role is fairly important. Not only does it need to construct
- *   the input scriptSigs and witnesses, but it SHOULD verify the signatures etc.
- *   Before running `psbt.finalizeAllInputs()` please run `psbt.validateSignaturesOfAllInputs()`
- *   Running any finalize method will delete any data in the input(s) that are no longer
- *   needed due to the finalized scripts containing the information.
- * Transaction Extractor: This role will perform some checks before returning a
- *   Transaction object. Such as fee rate not being larger than maximumFeeRate etc.
