# cdylib crates for C interoperability

Minimum Rust version: 1.10 for `rustc`

Minimum Rust version: 1.11 for `cargo`

If you're producing a library that you intend to be used from C (or another language through a C FFI), there's no need for Rust to include Rust-specific stuff in the final object code. For libraries like that, you'll want to use the `cdylib` crate type in your `Cargo.toml`:

    [lib]
    crate-type = ["cdylib"]

This will produce a smaller binary, with no Rust-specific information inside of it.
