Episode notes
Rust Production Code Basics
- Rust production code shares core operational needs with any language: reliability, observability, and recoverability.
- Rust-specific challenge lies in achieving these goals using its language and ecosystem tools.
Optimizing Rust Docker Images
- Use multi-stage Docker builds with a Rust compiler stage and a minimal runtime base image.
- Choose base image like Debian slim or scratch, ensuring needed system deps like OpenSSL are included.
Rust Compilation Profiles
- Release profile optimizes runtime speed and binary size at cost of slower compilation.
- Additional tuning like link time and profile-guided optimization can boost performance further.
