mac-addr

Lightweight, dependency-free, no_std compatible MAC address library
supporting both EUI-48 (MacAddr) and EUI-64 (MacAddr8).

Overview

It’s designed for portability and low-level use:

• no_std compatible
• Optional alloc for string formatting
• Optional serde support for serialization and deserialization
• Small, efficient, and FFI-safe

Usage

Add mac-addr to your dependencies

[dependencies]
mac-addr = "0.3"

Example

use mac_addr::{MacAddr, MacAddr8};

let mac6: MacAddr = "00:25:96:12:34:56".parse().unwrap();
assert_eq!(mac6.to_string(), "00:25:96:12:34:56");

// Convert EUI-48 -> EUI-64
let mac8 = MacAddr8::from_eui48(mac6);
assert_eq!(mac8.to_string(), "00:25:96:ff:fe:12:34:56");

// And back
assert_eq!(mac8.to_eui48().unwrap(), mac6);
