Third Party Rust Crates

This directory is where third party crate dependencies are managed. There are two sets of crates: ./crates_no_std and ./crates_std. These are cargo based “null” Rust libraries that exist solely to express which crates to expose to Bazel. ./rust_crates is a Bazel repository that exposes these crates to Bazel.

Adding a third party crate

1. Add the crate to either or both of ./crates_no_std and ./crates_std by running cargo add <crate_name> --features <additional_features> in the appropriate directory.
2. Update ./rust_crates/aliases.bzl by running cargo run -- --config config.toml > rust_crates/aliases.bzl in this directory.
