extern crate crypto;

use crypto::sha3::Sha3;

let mut shake_128 = Sha3::shake_128();
shake_128.input_str("123");
println!("shake_128 {}",shake_128.result_str());
}
//But It's noting

Take an example for Sha3::shake_128()

This crate is unmaintained and it's recommended to use modern alternatives instead. One such alternative is the sha3 crate from RustCrypto.
