Learning from YayoDrayber, I am sharing my CodeWars Kata which could also be a reference for myself in the future.

DESCRIPTION:

Complete the solution so that it reverses the string passed into it.

'world'  =>  'dlrow'
'word'   =>  'drow'

Starting code

fn solution(phrase: &str) -> String {
    unimplemented!();
}

My attempt

fn solution(phrase: &str) -> String {
    phrase.chars().rev().collect::<String>()
}

Best Practice

fn solution(phrase: &str) -> String {
    phrase.chars().rev().collect()
}

Shorter Code

fn solution(phrase: &str) -> String {
    phrase.rsplit("").collect::<String>()
}

My postkata snippet

fn reverse_string(phrase: &str) -> String {
    phrase.rsplit("").collect()
}
