// trybuild is a crate that essentially runs cargo on the provided files, and checks the output.
// Tests may suddenly fail after a new compiler release, and there's not much we can do about that.
// If the test suite fails because of trybuild:
// - Update your compiler to the latest stable version.
// - If it still fails, update the stderr snapshots. To do so, run the test suite with
// env variable TRYBUILD=overwrite, and submit the file changes in a PR.
