Function display_utils::lowercase

pub fn lowercase<T: Display>(object: T) -> Lowercase<T>

Print a Unicode-compliant lowercase version of the Display object.

Equivalent to str::to_lowercase, except it works on any Display object.

assert_eq!(lowercase("GRÜẞE JÜRGEN").to_string(), "grüße jürgen");

// Works with literally any Display object
assert_eq!(lowercase(join(&["HeLlO", "wOrLd"], ", ")).to_string(), "hello, world");
