Struct RegionRefinement 

pub struct RegionRefinement {
    pub removed: Vec<Vec<Range<usize>>>,
    pub added: Vec<Vec<Range<usize>>>,
}

The byte ranges that differ, per line, on each side of one hunk.

Per side, not per pair (DR.5). A hunk that removes one line and adds twelve has no line pairing to speak of, so the two sides carry independent per-line range lists: removed[i] describes the i-th removed line, added[j] the j-th added one, and neither implies the other’s length.

This replaced a Vec<Option<LineRefinement>> that was indexed by pair. That shape could not represent n removed against m added at all, which is why the old code declined those hunks outright rather than rendering them badly.

Fields

removed: Vec<Vec<Range<usize>>>

One entry per removed line, in order.

added: Vec<Vec<Range<usize>>>

One entry per added line, in order.

Implementations

impl RegionRefinement

pub fn is_empty(&self) -> bool

True when neither side has a single refined range — the value a declined region carries, and the one that renders exactly as it did before refinement existed.

pub fn removed_line(&self, i: usize) -> &[Range<usize>]

Refined ranges on the i-th removed line. Empty — never a panic — for an index past the end, so a consumer walking a baseline range that outruns the refinement degrades to “no refinement here” instead of falling over.

pub fn added_line(&self, j: usize) -> &[Range<usize>]

Refined ranges on the j-th added line. Same tolerance as Self::removed_line.
