1//! build-rs provides a strongly typed interface around the Cargo build script
2//! protocol. Cargo provides inputs to the build script by environment variable
3//! and accepts commands by printing to stdout.

5//! > This crate is maintained by the Cargo team for use by the wider
6//! > ecosystem. This crate follows semver compatibility for its APIs.
