ucfirst 0.1.0

Uppercase the first letter of a string
Documentation

This is the long-awaited Rust crate that solves the problem of uppercasing the first letter of a string in Rust.

Full disclosure: this solution was shamelessly lifted from the leading response over on StackOverflow by Shepmaster.

let lc_str = "apple";

// Using FromStr/parse and Display/to_string methods:
use ucfirst::Ucfirst;
let uc_str = lc_str.parse::<Ucfirst>().unwrap().to_string();
assert_eq!(uc_str, "Apple");

// Using ucfirst function:
use ucfirst::ucfirst;
let uc_str = ucfirst(lc_str);
assert_eq!(uc_str, "Apple");
