cook_rust

cook_rust turns one Cargo manifest into one portable Cook seal. Cargo remains the build scheduler; the module only derives the determinants needed to share the output of commands such as wasm-pack build safely.

use cook_rust

cook_rust.project("crates/web/Cargo.toml")

recipe wasm
    seal rust:project
    cook "packages/wasm/**" {
        wasm-pack build crates/web --out-dir packages/wasm
    }

rust:project includes every reachable local/path package under Cargo’s all-features graph, active ancestor and Cargo-home configuration, rustup override files and environment, and the content identities of the PATH-selected Cargo, configured compiler wrappers, and active toolchain’s real cargo and rustc binaries. Configuration and environment values are represented only by hashes; credentials are never serialized into the probe value. Registry and git dependency source trees are not included. Local package directories are tracked conservatively, excluding their target/ and .git/ directories.

Only one project may be registered per Cookfile. Build scripts that read undeclared files outside reachable local packages must be sealed separately. Local dependencies and active configuration outside the Cook workspace are rejected with an actionable error because Cook cannot track those files safely.
