Expand description
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
.
Structsยง

- Handles the writing of
HumanReadableErrorType::Default
andHumanReadableErrorType::Short

- An emitter that does nothing when emitting a non-fatal diagnostic. Fatal diagnostics are forwarded to
fatal_dcx
to avoid silent failures of rustc, as witnessed e.g. in issue #89358.
