Struct Set

pub struct Set<T: 'static>(/* private fields */);

An immutable set with lookup via a perfect hash function.

Constructable at compile time with a BuildSet. Unlike an OrderedSet, no iteration order is specified. Internally, this is a wrapper for phf::Set from the excellent phf crate.

This API requires the following crate feature to be activated: set

Implementations

impl<T> Set<T>

pub const fn len(&self) -> usize

pub const fn is_empty(&self) -> bool

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

where U: PhfHash + Eq + ?Sized, T: PhfBorrow<U>,

pub fn get_key<U>(&self, value: &U) -> Option<&T>

where U: PhfHash + Eq + ?Sized, T: PhfBorrow<U>,

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

pub const fn init_raw(set: Set<T>) -> Set<T>

An implementation detail. You shouldn’t need to call this function.
