cargo-chef is a cargo subcommand that speeds up Rust Docker builds by exploiting Docker layer caching. It extracts a recipe of the project's dependency manifests, builds dependencies in a separate cached layer, and avoids recompiling them when only source code changes.

Use cases

• speed up Rust Docker builds with layer caching
• cache Rust dependencies in Docker images
• avoid recompiling crates when only source changes
• optimize CI builds for Rust containers
• generate a requirements.txt-like recipe for Rust dependencies

When to choose

• you build Rust projects in Docker and rebuilds are slow
• your CI pipeline rebuilds Rust dependencies on every commit
• you want faster container image builds without restructuring your Dockerfile manually

When to avoid

• you don't build Rust in containers
• you want a tool to run locally on an existing codebase (it's designed for Docker build contexts)
• you use a build system that already caches dependencies effectively
