Struct SingletonSetStorage

pub struct SingletonSetStorage { /* private fields */ }

SetStorage types that can only inhabit a single value (like ()).

Trait Implementations

impl Clone for SingletonSetStorage

fn clone(&self) -> SingletonSetStorage

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Hash for SingletonSetStorage

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SingletonSetStorage

fn cmp(&self, other: &SingletonSetStorage) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SingletonSetStorage

fn eq(&self, other: &SingletonSetStorage) -> 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 PartialOrd for SingletonSetStorage

fn partial_cmp(&self, other: &SingletonSetStorage) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T> SetStorage<T> for SingletonSetStorage

where T: Default,

type Iter<'this> = IntoIter<T>

Immutable iterator over storage.

type IntoIter = IntoIter<T>

Owning iterator over the storage.

fn empty() -> Self

Construct empty storage.

fn len(&self) -> usize

Get the length of storage.

fn is_empty(&self) -> bool

Check if storage is empty.

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

This is the storage abstraction for Set::insert.

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

This is the storage abstraction for Set::contains.

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

This is the storage abstraction for Set::remove.

fn retain<F>(&mut self, func: F)

where F: FnMut(T) -> bool,

This is the storage abstraction for Set::retain.

fn clear(&mut self)

This is the storage abstraction for Set::clear.

fn iter(&self) -> Self::Iter<'_>

This is the storage abstraction for Set::iter.

fn into_iter(self) -> Self::IntoIter

This is the storage abstraction for Set::into_iter.
