[−][src]Trait umlauts::UmlautsOwned

pub trait UmlautsOwned {
    pub fn make_utf8_umlauts_lowercase(&mut self);
    pub fn make_utf8_umlauts_uppercase(&mut self);
}

Inplace string processing functions.

UnlautsInplaceExt adds inplace string processing functions for the german "Umlauts" 'ä', 'ö', 'ü', 'ß' and their uppercase variants (except for uppercase 'ß'). Because these functions dont resize their containers or shift the containing data, those methods are limited and should only be used if the higher performance is absolutely needed.

Required methods

`pub fn make_utf8_umlauts_lowercase(&mut self)`[src]

Lowercases alphabetic ASCII chars and UTF-8 umlauts.

Like make_ascii_lowercase but it will also make utf8 umlauts lowercase:

'Ä' -> 'ä'
'Ö' -> 'ö'
'Ü' -> 'ü'

Examples

extern crate umlauts;
use umlauts::UmlautsOwned;

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

`pub fn make_utf8_umlauts_uppercase(&mut self)`[src]

Upercases alphabetic ASCII chars and UTF-8 umlauts.

Like make_ascii_uppercase but it will also make utf8 umlauts uppercase:

'ä' -> 'Ä'
'ö' -> 'Ö'
'ü' -> 'Ü'

Examples

extern crate umlauts;
use umlauts::UmlautsOwned;

let mut s = "Öl Ärmel Übermut".as_bytes().to_vec();
s.make_utf8_umlauts_uppercase();
assert_eq!("ÖL ÄRMEL ÜBERMUT".as_bytes(), s);
