Struct HumanEmitter 

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>(writer: W, color: ColorChoice) -> HumanEmitter

where W: Write + Send + 'static,

Creates a new HumanEmitter that writes to given writer.

Note that a color choice of Auto will be treated as Never because the writer opaque at this point. Prefer calling AutoStream::choice on the writer if it is known before-hand.

pub fn test() -> HumanEmitter

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

pub fn stderr(color_choice: ColorChoice) -> HumanEmitter

Creates a new HumanEmitter that writes to stderr.

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

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) -> HumanEmitter

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.

pub fn human_kind(self, kind: HumanEmitterKind) -> HumanEmitter

Sets the human emitter kind (unicode vs short).

pub fn terminal_width(self, width: Option<usize>) -> HumanEmitter

Sets the terminal width for formatting.
