Function diff_index_to_worktree_with_options 

pub fn diff_index_to_worktree_with_options(
    odb: &Odb,
    index: &Index,
    work_tree: &Path,
    options: DiffIndexToWorktreeOptions,
) -> Result<Vec<DiffEntry>>

Compare the index against the working tree with optional racy-timestamp context.

This variant enables a stat-trust fast path: if an entry’s stat tuple matches and the mode is unchanged, the worktree blob hash is skipped unless the entry is racy relative to the supplied index mtime.

Parameters

• odb — object database (for hashing worktree files).
• index — the current index.
• work_tree — path to the working tree root.
• options — optional context for racy timestamp checks.

Errors

Returns errors from I/O or hashing.
