Struct phf::Set

source ·
pub struct Set<T: 'static> { /* private fields */ }
Expand description

An immutable set constructed at compile time.

§Note

The fields of this struct are public so that they may be initialized by the phf_set! macro and code generation. They are subject to change at any time and should never be accessed directly.

Implementations§

source§

impl<T> Set<T>

source

pub const fn len(&self) -> usize

Returns the number of elements in the Set.

source

pub const fn is_empty(&self) -> bool

Returns true if the Set contains no elements.

source

pub fn get_key<U>(&self, key: &U) -> Option<&T>
where U: Eq + PhfHash + ?Sized, T: PhfBorrow<U>,

Returns a reference to the set’s internal static instance of the given key.

This can be useful for interning schemes.

source

pub fn contains<U>(&self, value: &U) -> bool
where U: Eq + PhfHash + ?Sized, T: PhfBorrow<U>,

Returns true if value is in the Set.

source

pub fn iter(&self) -> Iter<'_, T>

Returns an iterator over the values in the set.

Values are returned in an arbitrary but fixed order.

source§

impl<T> Set<T>
where T: Eq + PhfHash + PhfBorrow<T>,

source

pub fn is_disjoint(&self, other: &Set<T>) -> bool

Returns true if other shares no elements with self.

source

pub fn is_subset(&self, other: &Set<T>) -> bool

Returns true if other contains all values in self.

source

pub fn is_superset(&self, other: &Set<T>) -> bool

Returns true if self contains all values in other.
