Function capture_diff

    alg: Algorithm,
    old: &Old,
    old_range: Range<usize>,
    new: &New,
    new_range: Range<usize>,

Expand description

Creates a diff between old and new with the given algorithm capturing the ops.

This is like diff but instead of using an arbitrary hook this will always use Compact + Replace + Capture and return the captured DiffOps.
