The number required ( usize isize ) is converted to a string ( String &str ) and back, in the Rust programming language.

    INT => STRING

     let i = 10000usize; //IN, TYPE:USIZE let mut i_str = i.to_string(); //STRING println!("{}", i_str); //RESULT=> 10000 i_str.push_str("len"); println!("{}", i_str); //RESULT=> 10000len

    & STR => INT

     let s = "1034"; let mut i = s.parse::<i32>().unwrap(); //IN STR, OUT I32 println!("{}", i); //RESULT=> 1034 i += 1024; println!("{}", i); //RESULT=> 2058 
       let my_string = "27".to_string(); // `parse()` works with `&str` and `String`! let my_int = my_string.parse::<usize>().unwrap(); let my_string = my_int.to_string();
