Required Methods§

Source

fn consume_hunk( &mut self, header: HunkHeader, lines: &[(DiffLineKind, &[u8])], ) -> Result<()>

Consume a single hunk which is represented by its lines, each of which contains a DiffLineKind and the original token bytes (&[u8]) for that line without the unified diff prefix character. The header specifies hunk offsets, which positions the lines in the old and new file respectively.

Note that crate::blob::UnifiedDiff will wrap its output in an std::io::Result. After this method returned its first error, it will not be called anymore.
