Struct OrderedSet 

pub struct OrderedSet<T: 'static> { /* private fields */ }

An order-preserving immutable set constructed at compile time.

Unlike a Set, iteration order is guaranteed to match the definition order.

Note

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

Implementations

impl<T> OrderedSet<T>

pub const fn len(&self) -> usize

Returns the number of elements in the OrderedSet.

pub const fn is_empty(&self) -> bool

Returns true if the OrderedSet contains no elements.

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.

pub fn get_index<U>(&self, key: &U) -> Option<usize>

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

Returns the index of the key within the list used to initialize the ordered set.

pub fn index(&self, index: usize) -> Option<&T>

Returns a reference to the key at an index within the list used to initialize the ordered set. See .get_index(key).

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

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

Returns true if value is in the OrderedSet.

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

Returns an iterator over the values in the set.

Values are returned in the same order in which they were defined.

impl<T> OrderedSet<T>

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

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

Returns true if other shares no elements with self.

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

Returns true if other contains all values in self.

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

Returns true if self contains all values in other.

Trait Implementations

impl<T> Debug for OrderedSet<T>

where T: Debug,

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T> IntoIterator for &'a OrderedSet<T>

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = Iter<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Iter<'a, T>

Creates an iterator from a value.

impl<T> PartialEq for OrderedSet<T>

where T: PartialEq,

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Eq for OrderedSet<T>

where T: Eq,

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
