Fields

diff_old_path: Option<String>

Path from diff --git old side (a/...) when present.

diff_new_path: Option<String>

Path from diff --git new side (b/...) when present.

old_path: Option<String>

Path on the old side (None for new files).

new_path: Option<String>

Path on the new side (None for deleted files).

saw_old_header: bool

Whether an explicit --- header line was present.

saw_new_header: bool

Whether an explicit +++ header line was present.

old_mode: Option<String>

Old mode from extended header.

new_mode: Option<String>

New mode from extended header.

old_mode_line: Option<usize>

Source line (1-based) of old mode / deleted file mode for diagnostics.

new_mode_line: Option<usize>

Source line (1-based) of new mode / new file mode for diagnostics.

is_new: bool

Whether this file is being newly created.

is_deleted: bool

Whether this file is being deleted.

is_rename: bool

Whether this is a rename.

is_copy: bool

Whether this is a copy.

similarity_index: Option<u32>

Similarity index (e.g., 90 for 90%).

dissimilarity_index: Option<u32>

Dissimilarity index for rewrites.

old_oid: Option<String>

Old blob OID from the index header (abbreviated).

new_oid: Option<String>

New blob OID from the index header (abbreviated).

binary_patch: Option<BinaryPatchPayload>

Parsed binary patch payload (GIT binary patch) if present.

is_binary: bool

Whether this is a binary change (GIT binary patch payload or a Binary files ... differ marker); stat/numstat show Bin / -.

hunks: Vec<Hunk>

Hunks to apply.

ws_rule: u32

Merged core.whitespace + whitespace attribute (Git ws_rule); 0 before assignment.

is_toplevel_relative: bool

Git patch->is_toplevel_relative: set for diff --git patches only. When false, paths are prefixed with the setup directory (work-tree-relative CWD) like prefix_patch in Git.

Implementations

impl FilePatch

pub fn effective_path(&self) -> Option<&str>

Effective path for the file. For deletions, use old_path (new is /dev/null). For additions, use new_path (old is /dev/null). Otherwise prefer new_path.

Trait Implementations

impl Clone for FilePatch

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FilePatch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
