cargo-check

name	cargo-check
description	Fast Rust compilation check. Use during active coding for quick type-check feedback without full codegen. Prefer over `cargo build` when you only need to verify types, borrows, and syntax.

Checking

cargo check

Workspace

cargo check --workspace

Specific package

cargo check -p <package>

Release mode

cargo check --release

Gotchas

• --workspace checks all packages; --all is deprecated — always use --workspace.
• Much faster than cargo build (skips codegen) but does not verify linking.
• Use during active editing cycles; switch to cargo build before claiming done.
• --all-targets includes tests, benches, and examples.
