pub struct EnumSet<E> { /* fields omitted */ }
A specialized set implementation to use enum types.
It is a logic error for an item to be modified in such a way that the transformation of the item to or from a usize, as determined by the CLike trait, changes while the item is in the set. This is normally only possible through Cell, RefCell, global state, I/O, or unsafe code.
impl<E:Â CLike> EnumSet<E>
[src]
fn new() -> EnumSet<E>Returns an empty EnumSet.
fn len(&self) -> usizeReturns the number of elements in the given EnumSet.
fn is_empty(&self) -> boolReturns true if the EnumSet is empty.
fn clear(&mut self)fn is_disjoint(&self, other: &EnumSet<E>) -> boolReturns false if the EnumSet contains any enum of the given EnumSet.
fn is_superset(&self, other: &EnumSet<E>) -> boolReturns true if a given EnumSet is included in this EnumSet.
fn is_subset(&self, other: &EnumSet<E>) -> boolReturns true if this EnumSet is included in the given EnumSet.
fn union(&self, e: EnumSet<E>) -> EnumSet<E>Returns the union of both EnumSets.
fn intersection(&self, e: EnumSet<E>) -> EnumSet<E>Returns the intersection of both EnumSets.
fn insert(&mut self, e: E) -> boolAdds an enum to the EnumSet, and returns true if it wasn't there before
fn remove(&mut self, e: &E) -> boolRemoves an enum from the EnumSet
fn contains(&self, e: &E) -> boolReturns true if an EnumSet contains a given enum.
fn iter(&self) -> Iter<E>Returns an iterator over an EnumSet.
