Bazel rules to test build errors.
rules_build_error provides Bazel implementations that let developers verify code that should not compile.
When executing bazel test, standard Bazel testing rules, like cc_test, will result in an error if a test code doesn’t compile. With rules_build_error, a bazel build command will instead fail when code does compile, indicating that the target is expected to raise a compilation error.
For more examples, see the example module.

The matcher struct allows specific error message matching criteria. Learn more in its readme.
