This crate tells you if you're in a CI environment or not. It does not tell you which you're in, but it makes a good effort to make sure to accurately tell you whether you're in one.

This crate is based on the @npmcli/ci-detect package.

If you need more information about the specific CI environment you're running in and you can handle a heavier dependency, please consider using ci_info instead.

Example

// You can call this repeatedly if you want to get the same result, cached.
let am_i_in_ci_right_now = is_ci::cached();

// If you expect your environment to change between calls, use this instead:
let checking_again_just_in_case = is_ci::uncached();
