Struct GitBaseline 

pub struct GitBaseline { /* private fields */ }

A DiffParticipantSource that reads file content from a specific git revision (e.g., "HEAD", "main~3") via git show <rev>:<path>.

snapshot() is called inside spawn_blocking by the diff subsystem, so the blocking I/O of the git show child process is acceptable.

Stores the git workdir path rather than a gix::Repository handle because gix::Repository is Send but not Sync (contains RefCells internally), and DiffParticipantSource requires Send + Sync.

Implementations

impl GitBaseline

pub fn new( workdir: impl Into<PathBuf>, rev: impl Into<String>, rel_path: impl Into<PathBuf>, ) -> Self

workdir — the repository working tree root. rev — the git revision (e.g., "HEAD", "main~3"). rel_path — file path relative to workdir.

Trait Implementations

impl Clone for GitBaseline

fn clone(&self) -> GitBaseline

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GitBaseline

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

Formats the value using the given formatter.

impl DiffParticipantSource for GitBaseline

fn snapshot(&self) -> Rope

Produce this participant’s rope. Called once per recompute; the implementor decides whether to clone a cached rope or rematerialise from a backing store.

fn buffer_id(&self) -> Option<BufferId>

D.8.d (2026-05-31): the buffer id this source is backed by, if any. Returns None for non-buffer sources (StaticSource, OnDiskSource, future GitSource); BufferSource overrides to return Some(buffer_id).
