Conversion between String, str, Vec<u8>, Vec<char> in Rust
use std::str;
fn main() {
// -- FROM: vec of chars --
let src1: Vec<char> = vec!['j','{','"','i','m','m','y','"','}'];
// to String
let string1: String = src1.iter().collect::<String>();
// to str
let str1: &str = &src1.iter().collect::<String>();
// to vec of byte
