[−][src]Struct langtag::PrivateUseSubtagsMut
Mutable reference to private use subtags.
Implementations
impl<'a> PrivateUseSubtagsMut<'a>[src]
pub fn as_ref(&self) -> &PrivateUseSubtags[src]
Returns a non-mutable reference to the private use subtags.
pub fn is_empty(&self) -> bool[src]
Checks if the subtag list is empty.
pub fn contains<T: AsRef<[u8]> + ?Sized>(&self, subtag: &T) -> bool[src]
Checks if the given subtag is present.
pub fn insert(&mut self, subtag: &PrivateUseSubtag) -> bool[src]
Insert a new subtag if it is not already present.
Return true if the subtag has been inserted,
and false if the subtag was already present.
pub fn remove<T: AsRef<[u8]> + ?Sized>(&mut self, subtag: &T) -> bool[src]
Remove all occurences of the given subtag.
Return true if the subtag was present and false otherwise.
