//! The [`VcsBackend`] trait that all VCS backends implement.
//!
//! This trait is `pub` so that downstream crates can implement custom
//! backends and inject them via [`endringer::repository::Repository::with_backend`].
//! The trait signature may change before v1.0.

/// All methods take `&self` and must be safe to call from multiple threads
