By default the action uses the following parts for key: - the github job_id (if add-job-id-key is "true"), - the rustc release / host / hash (for all installed toolchains when available), - the following values, if add-rust-environment-hash-key is "true": - the value of some compiler-specific environment variables (eg. RUSTFLAGS, etc), and - a hash of all Cargo.lock / Cargo.toml files found anywhere in the repository (if present). - a hash of all rust-toolchain / rust-toolchain.toml files in the root of the repository (if present). - a hash of all .cargo/config.toml files in the root of the repository (if present). And so, we only need to append something for the matrix-based job description.
