Struct collections::enum_set::EnumSet

pub struct EnumSet<E> {
    // some fields omitted
}

Unstable (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>

Unstable (enumset)

: matches collection reform specification, waiting for dust to settle

Returns an empty EnumSet.

fn len(&self) -> usize

Unstable (enumset)

: matches collection reform specification, waiting for dust to settle

Returns the number of elements in the given EnumSet.

fn is_empty(&self) -> bool

Unstable (enumset)

: matches collection reform specification, waiting for dust to settle

Returns true if the EnumSet is empty.

fn clear(&mut self)

Unstable (enumset)

: matches collection reform specification, waiting for dust to settle

fn is_disjoint(&self, other: &EnumSet<E>) -> bool

Unstable (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

Unstable (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

Unstable (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>

Unstable (enumset)

: matches collection reform specification, waiting for dust to settle

Returns the union of both EnumSets.

fn intersection(&self, e: EnumSet<E>) -> EnumSet<E>

Unstable (enumset)

: matches collection reform specification, waiting for dust to settle

Returns the intersection of both EnumSets.

fn insert(&mut self, e: E) -> bool

Unstable (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

Unstable (enumset)

: matches collection reform specification, waiting for dust to settle

Removes an enum from the EnumSet

fn contains(&self, e: &E) -> bool

Unstable (enumset)

: matches collection reform specification, waiting for dust to settle

Returns true if an EnumSet contains a given enum.

fn iter(&self) -> Iter<E>

Unstable (enumset)

: matches collection reform specification, waiting for dust to settle

Returns an iterator over an EnumSet.
