#![no_std]
//! This crate works by building a match at compile time which is then used to lookup in.

/// Lookup a manufacturer by a mac address.

/// # Example
/// ```rust
/// let manuf = macnuf::lookup("90:84:2B:12:34:56".parse().unwrap()).unwrap();
/// assert_eq!(manuf, "LEGO System A/S");
/// ```
