Talk to Cargo easily at build time, brought to you by Nikolai Vazquez.

This library provides:

  • Convenience macros for communicating with Cargo during the build.rs phrase. Cargo listens to certain build script outputs that dictate how it should behave.

  • An accessible location for seeing what script build outputs are available to emit.

  • Protection against typos that can be made when printing these formatted outputs directly yourself. Mistyping macro names will result in a compile failure.

Usage

This crate exposes the following macros:

Macro Output
pair!($key, $value) cargo:$key=$value
rerun_if_changed!($path) cargo:rerun-if-changed=$path
rerun_if_env_changed!($key) cargo:rerun-if-env-changed=$key
