[−][src]Struct icu::locid::extensions::private::Key
A single item used in a list of Private
extensions.
The key has to be an ASCII alphanumerical string no shorter than one character and no longer than eight.
Examples
use icu_locid::extensions::private::Key; let key1: Key = "Foo".parse() .expect("Failed to parse a Key."); assert_eq!(key1.as_str(), "foo");
Implementations
impl Key
[src]
pub fn from_bytes(v: &[u8]) -> Result<Key, ParserError>
[src]
A constructor which takes a utf8 slice, parses it and
produces a well-formed Key
.
Examples
use icu_locid::extensions::private::Key; let key = Key::from_bytes(b"foobar") .expect("Parsing failed."); assert_eq!(key.as_str(), "foobar");
pub fn as_str(&self) -> &str
[src]
A helper function for displaying
a Key
as a &str
.
Examples
use icu_locid::extensions::private::Key; let key = Key::from_bytes(b"foobar") .expect("Parsing failed."); assert_eq!(key.as_str(), "foobar");
Notice
: For many use cases, such as comparison,
Key
implements PartialEq<&str>
which allows for direct comparisons.
