Final Rust Code Listing

The final code listing looks like this:

use std::cmp::Ordering;
use std::convert::TryInto;
use std::io;


fn get_input(var: &mut String) -> i32 {
    io::stdin()
        .read_line(var)
        .expect("Failed to read line");

    var.chars()
        .count()
        .try_into()
        .expect("Length of name is too large!")
}

fn calculate_compatibility(name1_count: i32, name2_count: i32) -> f32 {
    match name1_count.cmp(&name2_count) {
        Ordering::Less => {
            ((name1_count as f32 / name2_count as f32) as f32 * 100.0) as f32
        },
        Ordering::Greater => {
            ((name2_count as f32 / name1_count as f32) as f32 * 100.0) as f32
        },
        Ordering::Equal => {
            50.0
        }
    }
}


fn main() {
    let mut name1 = String::new();
    let mut name2 = String::new();

    println!("Enter first person name: ");
    let name1_count = get_input(&mut name1);

    println!("Enter second person name: ");
    let name2_count = get_input(&mut name2);

    let compat_value = calculate_compatibility(name1_count, name2_count).floor();
    
    println!("Love compatibility between {} and {} is {}%", name1.trim(), name2.trim(), compat_value);
}

The final code can be gotten here, a repo of mine dedicated to learning Rust and its paradigms.
