rust-cargo-check

To speed up Rust compilation during iterative coding, use cargo check instead of a full build. This validates your types and code structure without generating executables or linking, providing fast feedback for refactoring and feature validation.

The difference is that cargo check validates types and compiles code without generating executables or linking, whereas cargo build performs a full build. Using cargo check is preferred for routine type-checking and quick validation during development to get faster feedback.

Yes, you need the Rust toolchain and cargo installed to run cargo check. The toolchain provides the necessary compiler components to validate your code types and ensure your refactoring or incremental changes compile correctly without producing a final executable.

Yes, you can use cargo check for safe iteration when refactoring Rust code. It performs routine type-checking and quick validation of incremental changes, ensuring your code compiles correctly without the overhead of code generation and linking.

You should not use cargo check when you need to generate executables or run tests, as it skips code generation and linking. It is designed for fast feedback during development and feature validation, so a full build is required to produce runnable artifacts.
