Abstraction over VCS operations needed by the diff module.

Required Methods

fn working_tree_changes( &self, base_ref: Option<&str>, ) -> Result<Vec<VcsFileChange>, DiffError>

Get changed files between working tree and a base ref.

fn changes_between_refs( &self, from_ref: &str, to_ref: &str, ) -> Result<Vec<VcsFileChange>, DiffError>

Get changed files between two refs (from_ref..to_ref).

fn read_file_at_ref( &self, path: &str, git_ref: &str, ) -> Result<Option<String>, DiffError>

Read file content at a specific ref. Returns None if file doesn’t exist or is binary.

fn commit_count(&self, from_ref: &str, to_ref: &str) -> Result<usize, DiffError>

Count commits between two refs.

fn resolve_ref(&self, refspec: &str) -> Result<bool, DiffError>

Check if a ref exists.

fn head_sha(&self) -> Result<String, DiffError>

Get HEAD commit SHA.

fn root_commit_sha(&self) -> Result<Option<String>, DiffError>

Find the root commit SHA (first commit with no parents).

Dyn Compatibility

This trait is dyn compatible.

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