Expand description

Canonical enumeration (ADR 0005: total, no exclusions, ever).

FROZEN ARGV. The byte format each method returns is what parse.rs, rename_view.rs and ultimately the frozen normaliser were validated against; changing a flag changes shape hashes and breaks real-corpus parity. Add a method, never edit one.

Required Methods§

Source

fn raw_records(&self, base: &str, head: &str) -> Result<Vec<u8>, EngineError>

diff-tree -r -z --raw --full-index --no-renames: authoritative modes, full oids, dispositions.

Source

fn canonical_patch( &self, base: &str, head: &str, ) -> Result<Vec<u8>, EngineError>

diff-tree -r -U0 --no-renames --no-color --no-ext-diff: the canonical patch. Every hunk in the system comes from here.

Source

fn rename_records(&self, base: &str, head: &str) -> Result<Vec<u8>, EngineError>

diff-tree -r -M -z --name-status: rename-detected annotations only (ADR 0003). Never affects what exists.

Dyn Compatibility§

This trait is dyn compatible.

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