Status Message in Rust - Gitpod version

This smart contract saves and records the status messages of NEAR accounts that call it.

Note: this README is specific to Gitpod and this example. For local development, please see README.md.

Using this contract

In Gitpod, a process has automatically created a new NEAR account that's useful for a quick (and likely temporary) usage. We've set an environment variable in Gitpod with the account name. At the bottom of this screen there's a Terminal.

You may see the NEAR account by running this command:

echo $CONTRACT_NAME

The next command will call the contract's set_status method:

near call $CONTRACT_NAME set_status '{"message": "aloha!"}' --accountId $CONTRACT_NAME

To retrieve the message from the contract, call get_status with the following:

near view $CONTRACT_NAME get_status '{"account_id": "'$CONTRACT_NAME'"}' --accountId $CONTRACT_NAME

Note that these status messages are stored per account in a HashMap. See src/lib.rs for the code. We can try the same steps with another account to verify. Note: we're adding NEW_ACCOUNT_NAME for the next couple steps.

There are two ways to create a new account:

  • the NEAR Wallet (as we did before)
  • near create_account NEW_ACCOUNT_NAME --masterAccount $CONTRACT_NAME

Now call the contract on the first account (where it's deployed):

near call $CONTRACT_NAME set_status '{"message": "bonjour"}' --accountId NEW_ACCOUNT_NAME
near view $CONTRACT_NAME get_status '{"account_id": "NEW_ACCOUNT_NAME"}'

Returns bonjour.

Make sure the original status remains:

near view $CONTRACT_NAME get_status '{"account_id": "$CONTRACT_NAME"}'

Now that you've seen this working in Gitpod, feel free to clone this repository and use it as a starting point for your own project.

Testing

To test run:

cargo test --package status-message -- --nocapture
