User Agent Parser

Simple implementation of the user agent parser based on the ua-parser/specification.

Usage

use uaparser_rs::UAParser;

let uap = UAParser::from_yaml("./regexes.yaml").unwrap();
let ua_str = "Mozilla/5.0 (Linux; Android 4.0.1; Galaxy Nexus Build/ITL41F) AppleWebKit 537.31 (KHTML, like Gecko) Chrome/26.0.1410.58 Mobile Safari/537.31";

let client = uap.parse(ua_str);

/*
  client {
    user_agent: {
      family,
      major,
      minor,
      patch,
      patch_minor,
    },
    os: {
      family,
      major,
      minor,
      patch,
      patch_minor,
    },
    device: {
      family,
      brand,
