Struct Renderer 

pub struct Renderer<'a> { /* private fields */ }

Renders diagnostics in the §8.2 layout.

The renderer borrows a SourceMap for source snippets and line/column conversion; it holds a style::Palette that decides whether the output is plain (the default, for snapshot-stable tests) or ANSI-styled. It is cheap to construct per render.

Implementations

impl<'a> Renderer<'a>

pub fn new(source: &'a SourceMap) -> Renderer<'a>

A plain-text renderer (no ANSI). The default for snapshot tests, which must stay byte-stable regardless of terminal state.

pub fn new_styled(source: &'a SourceMap, palette: Palette) -> Renderer<'a>

A renderer that styles its output when palette is style::Palette::styled.

pub fn render(&self, diag: &Diagnostic, out: &mut String)

Render one diagnostic into out.
