I'm currently using https://github.com/rust-lang/git2-rs to interact with git in my software. Are you aiming to have a stable api that could act as a pure-rust replacement for that at some point in the future?
It is my hope that the quality and stability will be high enough to convince people [in the Rust ecosystem] to move away from libgit2 and instead contribute to the maintenance and development of gitoxide, rewarding everyone with better performance and improved usability.
