# macaddr > MAC address types for Rust [](https://crates.io/crates/macaddr) [](https://docs.rs/macaddr) [](https://github.com/svartalf/rust-macaddr/actions) [](https://coveralls.io/github/svartalf/rust-macaddr?branch=master)    This crate provides types for a [MAC address](https://en.wikipedia.org/wiki/MAC_address) identifiers, both in IEEE *EUI-48* and *EUI-64* formats. It is like a [`std::net::SocketAddr`](https://doc.rust-lang.org/std/net/enum.SocketAddr.html) enum with a [`std::net::SocketAddrV4`](https://doc.rust-lang.org/std/net/struct.SocketAddrV4.html) and [`std::net::SocketAddrV6`](https://doc.rust-lang.org/std/net/struct.SocketAddrV6.html) members, but for MAC addresses instead. Obviously, MAC address can be represented as a `[u8; 6]` or `[u8; 8]`, but it is error-prone and inconvenient, so here they are — [MacAddr6](https://docs.rs/macaddr/latest/macaddr/struct.MacAddr6.html) and [MacAddr8](https://docs.rs/macaddr/latest/macaddr/struct.MacAddr8.html) structs with helpful methods and standard Rust traits implementations, intended to be the first-class Rust objects. And it is `serde`- and `no_std`-friendly also! ## Installation Add this to your `Cargo.toml` ```toml [dependencies] macaddr = "1.0" ``` ## Usage Check out the [documentation](https://docs.rs/macaddr) for each type available, all of them have a plenty of examples. ## License Licensed under either of [Apache License 2.0](https://github.com/svartalf/rust-macaddr/blob/master/LICENSE-APACHE) or [MIT license](https://github.com/svartalf/rust-macaddr/blob/master/LICENSE-MIT) at your option.
