Trait LineOriginSource 

pub trait LineOriginSource {
    // Required method
    fn origins(
        &self,
        rev: &str,
        path: &str,
        lines: &[u32],
    ) -> Result<Vec<(u32, String)>>;
}

Pluggable line-origin seam (roadmap’s “pluggable SZZ”). Given a file at a revision, returns for each requested 1-based line the commit that last introduced it. The production impl (CLI) shells git blame --porcelain; tests use an in-memory fake.

Required Methods

fn origins( &self, rev: &str, path: &str, lines: &[u32], ) -> Result<Vec<(u32, String)>>

Blame path at rev for the given 1-based lines, returning (line, introducing_commit) pairs. Implementations may return fewer pairs than requested lines (e.g. a line beyond EOF at rev); callers must not assume a 1:1 return count.

Errors

Any I/O or subprocess failure the backend hits reading path at rev. Callers treat this as a skip-with-log, never fatal.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
