Module emitter

The current rustc diagnostics emitter.

An Emitter takes care of generating the output from a Diag struct.

There are various Emitter implementations that generate different output formats such as JSON and human readable output.

The output types are defined in rustc_session::config::ErrorOutputType.

• Buffy 🔒
• FileWithAnnotatedLines 🔒
