Get the first letters of words in a sentence

  • A+

How I could get the first letters from a sentence; example: "Rust is a fast reliable programming language" should return the output riafrpl.

fn main() {     let string: &'static str = "Rust is a fast reliable programming language";     println!("First letters: {}", string); } 

let initials: String = string     .split(" ")                     // create an iterator, yielding words     .flat_map(|s| s.chars().nth(0)) // get the first char of each word     .collect();                     // collect the result into a String
