pub struct HumanEmitter { /* private fields */ }

Diagnostic emitter that emits to an arbitrary io::Write writer in human-readable format.

Implementations

impl HumanEmitter

pub fn new<W: Write + Send + 'static>(writer: W, color: ColorChoice) -> Self

Creates a new HumanEmitter that writes to given writer.

pub fn test() -> Self

Creates a new HumanEmitter that writes to stderr, for use in tests.

pub fn stderr(color_choice: ColorChoice) -> Self

Creates a new HumanEmitter that writes to stderr.

pub fn source_map(self, source_map: Option<Arc<SourceMap>>) -> Self

Sets the source map.

pub fn set_source_map(&mut self, source_map: Option<Arc<SourceMap>>)

Sets the source map.

pub fn ui_testing(self, yes: bool) -> Self

Sets whether to emit diagnostics in a way that is suitable for UI testing.

pub fn set_ui_testing(&mut self, yes: bool)

Sets whether to emit diagnostics in a way that is suitable for UI testing.
