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.
Structs§
- Buffy 🔒
- Fatal
Only Emitter - An emitter that does nothing when emitting a non-fatal diagnostic.
Fatal diagnostics are forwarded to
fatal_emitterto avoid silent failures of rustc, as witnessed e.g. in issue #89358. - File
With 🔒Annotated Lines - Human
Emitter - Handles the writing of
HumanReadableErrorType::DefaultandHumanReadableErrorType::Short - Margin 🔒
- Silent
Emitter - Underline

Constants§
- ANONYMIZED_
LINE_ 🔒NUM - BRIGHT_
BLUE 🔒 - On Windows, BRIGHT_BLUE is hard to read on black. Use cyan instead.
- DEFAULT_
COLUMN_ 🔒WIDTH - Default column width, used in tests and when terminal dimensions cannot be determined.
- MAX_
SUGGESTIONS - Maximum number of suggestions to be shown
- OUTPUT_
