Trait WriteStyle 

pub trait WriteStyle: GeneralWrite {
    // Required methods
    fn set_header(&mut self, severity: Severity) -> GeneralWriteResult;
    fn set_header_message(&mut self) -> GeneralWriteResult;
    fn set_line_number(&mut self) -> GeneralWriteResult;
    fn set_note_bullet(&mut self) -> GeneralWriteResult;
    fn set_source_border(&mut self) -> GeneralWriteResult;
    fn set_label(
        &mut self,
        severity: Severity,
        label_style: LabelStyle,
    ) -> GeneralWriteResult;
    fn reset(&mut self) -> GeneralWriteResult;
}

A writer that can apply styling for different parts of a diagnostic renderer.

Implementations

• PlainWriter<W> - no-op styling, plain text output
• StylesWriter<W> - custom styles (requires termcolor feature)
• T: WriteColor - blanket impl using default styles (requires termcolor feature)

Required Methods

fn set_header(&mut self, severity: Severity) -> GeneralWriteResult

fn set_header_message(&mut self) -> GeneralWriteResult

fn set_line_number(&mut self) -> GeneralWriteResult

fn set_note_bullet(&mut self) -> GeneralWriteResult

fn set_source_border(&mut self) -> GeneralWriteResult

fn set_label( &mut self, severity: Severity, label_style: LabelStyle, ) -> GeneralWriteResult

fn reset(&mut self) -> GeneralWriteResult

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
