# `block2` [![Latest version](https://badgen.net/crates/v/block2)](https://crates.io/crates/block2) [![License](https://badgen.net/badge/license/MIT/blue)](https://github.com/madsmtm/objc2/blob/master/LICENSE.txt) [![Documentation](https://docs.rs/block2/badge.svg)](https://docs.rs/block2/) [![CI](https://github.com/madsmtm/objc2/actions/workflows/ci.yml/badge.svg)](https://github.com/madsmtm/objc2/actions/workflows/ci.yml) Apple's C language extension of blocks in Rust. This crate provides functionality for interracting with C blocks, which is the C-equivalent of Rust's closures. They are _technically_ not limited to only being used in Objective-C, though in practice it's likely the only place you'll ever encounter them. See [the docs](https://docs.rs/block2/) for a more thorough overview. This crate is part of the [`objc2` project](https://github.com/madsmtm/objc2), see that for related crates.
