1//! A crate providing foundational capabilities to other `git-*` crates with trade-offs between compile time, binary size or speed
2//! selectable using cargo feature toggles.
3//!
4//! It's designed to allow the application level crate to configure feature toggles, affecting all other `git-*` crates using
5//! this one.
6//!
7//! Thus all features provided here commonly have a 'cheap' base implementation, with the option to pull in
8//! counterparts with higher performance.
9//! ## Feature Flags
