cargo-verify-project

Check correctness of a Cargo.toml manifest

TLDR

Verify current project manifest

$ cargo verify-project

Verify specific manifest

$ cargo verify-project --manifest-path [path/to/Cargo.toml]

Verify with locked dependencies

$ cargo verify-project --locked

Verify offline (no network access)

$ cargo verify-project --frozen

cargo verify-project parses and validates the local Cargo.toml manifest file. It outputs a JSON object indicating whether the manifest is syntactically correct and contains all required fields, along with error details on failure.This command is useful in CI/CD pipelines and pre-commit hooks for catching manifest errors early. It checks syntax correctness, valid dependency specifications, proper metadata formatting, and required fields. It does not verify that dependencies actually exist on a registry, only that the manifest itself is well-formed. The exit status is 0 for valid manifests and 1 for invalid ones.
