BlameCache

Struct BlameCache 

Source
pub struct BlameCache { /* private fields */ }
Expand description

Per-run cache of git blame output, shared across rules so multiple git_blame_age rules over overlapping paths: re-use the parsed result instead of re-shelling-out.

Constructed once per Engine::run when at least one rule reports wants_git_blame(). Lookups lock once per (path, miss) — git blame itself dwarfs any lock contention (process spawn + read of full file history). The cache also memoises failures (file untracked, blame exited non-zero) so a rule iterating thousands of out-of-scope files doesn’t re-probe each one repeatedly.

Implementations§

Source§

impl BlameCache

Source

pub fn new(root: PathBuf) -> Self

Source

pub fn get(&self, rel_path: &Path) -> Option<Arc<Vec<BlameLine>>>

Return the blame for rel_path, computing once and caching forever (within this run). None means blame failed for this path — the caller silently no-ops, by the rule-kind’s advisory posture.
