Parser-independent syntax highlighting seam consumed by the Base editor.

Implementations own parsing, incremental state, and language-specific behavior. Base only asks for styled ranges and fold candidates.

Required Methods

fn language(&self) -> SharedString

fn update( &mut self, edit: Option<InputEdit>, text: &Rope, folding: bool, window: &mut Window, cx: &mut Context<'_, InputBaseState<EditorMode>>, )

fn styles( &self, range: &Range<usize>, resolver: &dyn HighlightStyleResolver, ) -> Vec<(Range<usize>, HighlightStyle)>

Return ordered, non-overlapping style runs that fully cover range. Use HighlightStyle::default for text without a semantic style.

fn fold_ranges(&self, text: &Rope) -> Vec<FoldRange>

Provided Methods

fn fold_ranges_for_edit( &self, range: Range<usize>, text: &Rope, ) -> Vec<FoldRange>

Dyn Compatibility

This trait is dyn compatible.

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