Struct collections::enum_set::EnumSet
[−]
[src]
pub struct EnumSet<E> {
// some fields omitted
}enumset): matches collection reform specification, waiting for dust to settle
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.
Methods
impl<E: CLike> EnumSet<E>
fn new() -> EnumSet<E>
enumset): matches collection reform specification, waiting for dust to settle
Returns an empty EnumSet.
fn len(&self) -> usize
enumset): matches collection reform specification, waiting for dust to settle
Returns the number of elements in the given EnumSet.
fn is_empty(&self) -> bool
enumset): matches collection reform specification, waiting for dust to settle
Returns true if the EnumSet is empty.
fn clear(&mut self)
enumset): matches collection reform specification, waiting for dust to settle
fn is_disjoint(&self, other: &EnumSet<E>) -> bool
enumset): matches collection reform specification, waiting for dust to settle
Returns false if the EnumSet contains any enum of the given EnumSet.
fn is_superset(&self, other: &EnumSet<E>) -> bool
enumset): matches collection reform specification, waiting for dust to settle
Returns true if a given EnumSet is included in this EnumSet.
fn is_subset(&self, other: &EnumSet<E>) -> bool
enumset): matches collection reform specification, waiting for dust to settle
Returns true if this EnumSet is included in the given EnumSet.
fn union(&self, e: EnumSet<E>) -> EnumSet<E>
enumset): matches collection reform specification, waiting for dust to settle
Returns the union of both EnumSets.
fn intersection(&self, e: EnumSet<E>) -> EnumSet<E>
enumset): matches collection reform specification, waiting for dust to settle
Returns the intersection of both EnumSets.
fn insert(&mut self, e: E) -> bool
enumset): matches collection reform specification, waiting for dust to settle
Adds an enum to the EnumSet, and returns true if it wasn't there before
fn remove(&mut self, e: &E) -> bool
enumset): matches collection reform specification, waiting for dust to settle
Removes an enum from the EnumSet
fn contains(&self, e: &E) -> bool
enumset): matches collection reform specification, waiting for dust to settle
Returns true if an EnumSet contains a given enum.
fn iter(&self) -> Iter<E>
enumset): matches collection reform specification, waiting for dust to settle
Returns an iterator over an EnumSet.
