[−][src]Struct langtag::ExtensionsMut
Mutable reference to extension subtags.
Implementations
impl<'a> ExtensionsMut<'a>[src]
pub fn insert(&mut self, singleton: Singleton, subtag: &ExtensionSubtag) -> bool[src]
Insert a new subtag for the given extension singleton without duplication.
Returns true if the extension subtag has been added,
or false if it was already present.
pub fn remove(&mut self, singleton: Singleton) -> bool[src]
Remove the extension identified by the given singleton.
Return true if the extension was present and false otherwise
(in which case the language tag is left unchanged).
pub fn remove_subtag<T: AsRef<[u8]> + ?Sized>(
&mut self,
singleton: Singleton,
subtag: &T
) -> bool[src]
&mut self,
singleton: Singleton,
subtag: &T
) -> bool
Remove the given extension subtag.
Return true if the extension subtag was present and false otherwise
(in which case the language tag is left unchanged).
