Struct FileDiff 

pub struct FileDiff {
    pub old_path: Option<String>,
    pub new_path: String,
    pub is_new: bool,
    pub is_rename: bool,
    pub added: BTreeSet<u32>,
    pub removed: BTreeSet<u32>,
    /* private fields */
}

Per-file diff information.

Fields

old_path: Option<String>

Old-side (base) path. Differs from new_path on a rename; None for an added file.

new_path: String

New-side (head) path.

is_new: bool

Whether the file is newly added in head.

is_rename: bool

Whether the file was renamed (and possibly modified).

added: BTreeSet<u32>

New-side line numbers added or modified by the diff.

removed: BTreeSet<u32>

Old-side line numbers removed by the diff.

Implementations

impl FileDiff

pub fn new( new_path: impl Into<String>, old_path: Option<String>, is_new: bool, is_rename: bool, added: BTreeSet<u32>, removed: BTreeSet<u32>, ) -> Self

Builds a FileDiff with only added/removed line sets and no hunk alignment. Used to construct diffs programmatically and in tests; the git2-driven path uses DiffModel::from_diff which also records hunks.

pub fn map_base_to_head(&self, old_line: u32) -> Option<u32>

Maps an unchanged base-side line to its head-side line number.

Returns None when the base line was removed or modified (i.e. it has no unchanged counterpart in head). Context lines inside hunks use the exact pairs git2 reported; lines outside every hunk use the cumulative hunk offset.

Trait Implementations

impl Clone for FileDiff

fn clone(&self) -> FileDiff

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileDiff

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

Formats the value using the given formatter.
