Struct ULocMut

pub struct ULocMut { /* private fields */ }

ULocMut is a mutable companion to ULoc.

It has methods that allow one to create a different ULoc by adding and removing keywords to the locale identifier. You can only create a ULocMut by converting from an existing ULoc by calling ULocMut::from. And once you are done changing it, you can only convert it back with ULoc::from.

ULocMut is not meant to have comprehensive coverage of mutation options. They may be added as necessary.

Implementations

impl ULocMut

pub fn set_unicode_keyvalue(&mut self, key: &str, value: &str) -> Option<String>

Sets the specified unicode extension keyvalue. Only valid keys can be set, inserting an invalid extension key does not change ULocMut.

pub fn remove_unicode_keyvalue(&mut self, key: &str) -> Option<String>

Removes the specified unicode extension keyvalue. Only valid keys can be removed, attempting to remove an invalid extension key does not change ULocMut.
