bazel_monorepo_go_rust

This repository contains a monorepo, polyglot project consisting of a library for Go and Rust.
These libraries can be built using the appropriate native tool -- go build or Cargo -- and Bazel.
The source of truth for dependencies are the go.mod/vendors and Cargo files.
The Makefile contains many queries and commands for using the native tools for Go and Rust within Bazel as well as Bazel commands.

Valid Bazel Labels

• //pkg/golang:srcs
• //pkg/golang/src/grpc_client_lib:grpc_client_lib
• //pkg/golang/src/grpc_client_lib:grpc_client_lib_test
• //pkg/rust/src:srcs
• //pkg/rust/src/grpc_client_lib:grpc_client_lib
• //pkg/rust/src/grpc_client_lib:grpc_client_lib_test

To Change Go's and Rust's Versions

• Execute the set_golang_version command in the Makefile.
• Execute the set_rust_version command in the Makefile.

To Add A New Go Project

• Create a directory in /pkg/golang/src for the new Go project.
• Clone the files from grpc_client_lib to the new project's directory.
• Amend the files for the new project's needs.
• Add the relative path to the new project to the use() in go.work.
  • i.e. /pkg/golang/src/mynewproject
• You may want to clone the build_grpc_golang_client_lib command in the Makefile for directly building the new project.
• Verify that you can build the Go projects by executing the go_build_all (go build used) command in the Makefile.
• Verify that you can build the Go projects by executing the build_all (bazel used) command in the Makefile.

To Add A New Rust Project

• Create a directory in /pkg/rust/src for the new Rust project.
• Clone the files from grpc_client_lib to the new project's directory.
• Amend the files for the new project's needs.
• Add the bazel target to the new project to the crates_repository.manifests block in the WORKSPACE file.

crates_repository( name = "crate_index", cargo_lockfile = "//:Cargo.lock", lockfile = "//:cargo-bazel-lock.json", manifests = [ "//:Cargo.toml", "//:pkg/rust/src/grpc_client_lib/Cargo.toml", "//:pkg/rust/src/mynewproject/Cargo.toml", ], )

• You may want to clone the build_grpc_rust_client_lib command in the Makefile for directly building the new project.
• Add the relative path to the new project to the workspace.members block in Cargo.toml file.

[workspace] resolver = "2" members = [ "pkg/rust/src/grpc_client_lib", "pkg/rust/src/mynewproject", ]

• Verify that you can build the Rust projects by executing the rust_build_all (Cargo used) command in the Makefile.
• Verify that you can build the Rust projects by executing the build_all (bazel used) command in the Makefile.
