Example

use mimic_rs::ClientHints;

let ua = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36";
let hints = ClientHints::from_ua(ua).unwrap();

println!("sec-ch-ua: {}", hints.sec_ch_ua());
println!("sec-ch-ua-mobile: {}", hints.sec_ch_ua_mobile());
println!("sec-ch-ua-platform: {}", hints.sec_ch_ua_platform());
