Struct enumset::EnumSet

pub struct EnumSet<T: EnumSetType> { /* fields omitted */ }

An efficient set type for enums created with the enum_set_type! macro.

Methods

impl<T: EnumSetType> EnumSet<T>

pub fn new() -> Self

Returns an empty set.

pub fn only(t: T) -> Self

Returns a set containing a single value.

pub fn empty() -> Self

Returns an empty set.

pub fn all() -> Self

Returns a set with all bits set.

pub fn bit_width() -> u8

Total number of bits this enumset uses. Note that the actual amount of space used is rounded up to the next highest integer type (u8, u16, u32, u64, or u128).

pub fn to_bits(&self) -> u128

Returns the raw bits of this set

Panics

If bits not in the enum are set.

pub fn len(&self) -> usize

Returns the number of values in this set.

pub fn is_empty(&self) -> bool

Checks if the set is empty.

pub fn clear(&mut self)

Removes all elements from the set.

pub fn is_disjoint(&self, other: Self) -> bool

Checks if this set shares no elements with another.

pub fn is_superset(&self, other: Self) -> bool

Checks if all elements in another set are in this set.

pub fn is_subset(&self, other: Self) -> bool

Checks if all elements of this set are in another set.

pub fn union(&self, other: Self) -> Self

Returns a set containing the union of all elements in both sets.

pub fn intersection(&self, other: Self) -> Self

Returns a set containing all elements in common with another set.

pub fn difference(&self, other: Self) -> Self

Returns a set with all elements of the other set removed.

pub fn symmetrical_difference(&self, other: Self) -> Self

Returns a set with all elements not contained in both sets.

pub fn complement(&self) -> Self

Returns a set containing all elements not in this set.

pub fn contains(&self, value: T) -> bool

Checks whether this set contains a value.

pub fn insert(&mut self, value: T) -> bool

Adds a value to this set.

pub fn remove(&mut self, value: T) -> bool

Removes a value from this set.

pub fn insert_all(&mut self, other: Self)

Adds all elements in another set to this one.

pub fn remove_all(&mut self, other: Self)
