Rust library for german umlauts

Usage

# Cargo.toml

# Safe without manipulating &mut str
[dependencies]
umlauts = "0.1"

# Unsafe conversions with the ability to manipulate &mut str
umlauts = { version = "0.1", features = [ "unsafe" ] }

Examples

extern crate umlauts;

use umlauts::UmlautsOwned;

let mut s = "Öl Ärmel Übermut".to_string();
s.make_utf8_umlauts_lowercase();
assert_eq!("öl ärmel übermut", s);

Unsafe Features

&mut str manipulation

By default, this crate itself does not use unsafe features, except from the memchr dependency. To allow manipulating of references to String and &mut str, the unsafe feature can be used. As the manipulating functions operate on &mut [u8] and will always return valid UTF-8 if valid UTF-8 is given, those unsafe features should perform the same.
