git-indexer 0.2.1

# git-indexer

A Rust library for extracting git repository information (branches, commits, and file diffs).

## Installation

Add this to your `Cargo.toml`:

```toml
[dependencies]
git-indexer = "0.1.0"
```

## Usage

Extract git information from a repository:

```rust
use git_indexer::extraction::extract;
use std::path::Path;

fn main() -> git_indexer::Result<()> {
    let git_info = extract(Path::new("/path/to/repo"))?;

    println!("Branches: {}", git_info.branches.len());
    println!("Commits: {}", git_info.commits.len());

    for commit in &git_info.commits {
        println!("{}: {}", &commit.id[..8], commit.message);
    }

    Ok(())
}
```

## What It Extracts

### Branches (`BranchInfo`)
- Branch name (local and remote)
- Current HEAD indicator
- Commit SHA the branch points to

### Commits (`CommitInfo`)
- Commit SHA
- Message (title)
- Author (name and email)
- Timestamp
- Parent commit SHAs
- File changes

### File Changes (`FileChange`)
- File path
- Change type (Added, Deleted, Modified, Renamed, Copied)
- Diff hunks with line-by-line changes

## Technical Details

- Pure Rust git implementation via `gix`
- Efficient diff generation with `imara-diff` (Histogram algorithm)
- Binary file detection (skips diff for binary files)
- File size limit: 10MB per file
