Struct HunkRenderOptions 

pub struct HunkRenderOptions<'a, 'h> {
    pub context: usize,
    pub interhunk: usize,
    pub heading: Option<&'a mut HeadingFn<'h>>,
    pub colors: Option<RenderColors<'a>>,
    pub word_diff: Option<&'a mut dyn HunkWordDiff>,
    pub ws_error: Option<WsErrorHighlight>,
}

Hunk-shaping and styling options for render_hunks.

Lifetimes are split so the funcname / word-diff hooks can be borrowed mutably while colors is borrowed shared.

Fields

context: usize

Lines of context around each change (-U<n>, default DEFAULT_CONTEXT).

interhunk: usize

Extra inter-hunk merging distance (--inter-hunk-context).

heading: Option<&'a mut HeadingFn<'h>>

Per-line section-heading classifier; None emits headerless hunks.

colors: Option<RenderColors<'a>>

ANSI palette when color output is enabled.

word_diff: Option<&'a mut dyn HunkWordDiff>

Word-diff body hook (replaces the +/- line bodies of each hunk).

ws_error: Option<WsErrorHighlight>

--ws-error-highlight configuration: when set and colors are on, the renderer paints whitespace errors on the selected line kinds with colors.whitespace (git’s emit_line_ws_markup). None disables it.

Trait Implementations

impl Default for HunkRenderOptions<'_, '_>

fn default() -> Self

Returns the “default value” for a type.
