Rust Lang Packages(Crates)

Some good crates to start with are:

1. clap : for argument parsing
2. serde : for file formats (eg JSON)
3. errors - anyhow or thiserror 6 for easy error types
4. tracing + tracing-subscriber : for logging/instrumentation.
5. tokyo: async

6. shell & scripts: xshell or duct

Local dev

• Auto rebuild on code change

  cargo install cargo-watch
  cargo watch -x run

e.g. Cargo.toml

• 2023 web client
