strings
Instructions
Create a function which receives a string slice and returns the number of characters in that string.
Expected Function
pub fn char_length(s: &str) -> usize {
}
Usage
Here is a program to test your function.
use strings::*;
fn main() {
println!("length of {} = {}", "❤", char_length("❤"));
println!("length of {} = {}", "形声字", char_length("形聲字"));
println!("length of {} = {}", "change", char_length("change"));
println!("length of {} = {}", "😍", char_length("😍"));
}
And its output
$ cargo run
length of ❤ = 1
length of 形声字 = 3
length of change = 6
length of 😍 = 1
$
