The cargo verify-project command checks the integrity of a Rust package's contents on disk without compiling the code. It validates the package metadata in Cargo.toml, ensures all declared files exist, verifies file checksums against Cargo.lock, and confirms the local .crate file matches the registry version.

This is particularly useful in continuous integration pipelines or after switching Git branches, where you want to confirm the project files are correct before a full build. It detects issues like missing files, corrupted downloads, or metadata inconsistencies quickly, saving time on expensive compilation steps.

Unlike cargo check, which compiles for type-checking, verify-project focuses solely on package structure and checksums, making it lightweight and fast.

Does not compile or type-check code; only verifies files and metadata. Requires Cargo.lock for checksum validation.

cargo verify-project
Verifies the current package.

cargo verify-project --manifest-path ./myproj/Cargo.toml
Verifies a specific workspace member.

Introduced in Cargo 1.29.0 (2018) as a stable command to enable fast package verification, evolving from earlier unstable features for CI efficiency.
