一、String::from_utf8

fn main() {

    let bytes = vec![0x41, 0x42, 0x43];

    let s = String::from_utf8(bytes).expect("Found invalid UTF-8");

    println!("{}", s);

}

二、String::from_utf8_lossy

fn main() {

    let buf = &[0x41u8, 0x41u8, 0x42u8];

    let s = String::from_utf8_lossy(buf);

    println!("result: {}", s);

}
