block2

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 for a more thorough overview.

This crate is part of the objc2 project, see that for related crates.
