## What it is
git2-rs provides safe, idiomatic Rust bindings to the libgit2 C library for reading and writing git repositories. It offers automatic resource management, strong typing, and optional HTTPS/SSH network support via feature flags.

## Use cases
- programmatically read and write git repositories from Rust
- clone remote git repositories in a Rust application
- build a custom git client or tooling in Rust
- inspect commits, branches, and refs without shelling out to git
- embed git functionality in a Rust CLI or service

## When to choose
- you need fast, in-process git operations in Rust without invoking the git binary
- you want memory-safe, threadsafe bindings with automatic resource management
- you need fine-grained control over repository internals like objects, refs, and diffs

## When to avoid
- you just need to run simple git commands - shelling out to the git CLI may be simpler
- you need every libgit2 API - some bindings are still missing
- you want a pure-Rust implementation without C dependencies - consider gitoxide instead

## Facets
- artifact type: library
- maturity: stable
- function: version-control, developer-tools, sdk
- domain: version-control, developer-tools, cross-platform
- platform: rust, cross-platform, windows
- tags: libgit2, git, bindings, ffi, cargo-crate, linux, macos
