Struct DefaultHashable

pub struct DefaultHashable<H: Hash>(pub H);

A wrapper type that provides Hashable for any type that is Hash.

As part of using Registry, the chosen key type must implement Hashable. For use cases where performance is not the utmost concern and there is no desire to deal with pre-hashing keys, DefaultHashable can be used to wrap the key type and provide the implementation of Hashable so long as H itself is Hash.

Trait Implementations

impl<H: Clone + Hash> Clone for DefaultHashable<H>

fn clone(&self) -> DefaultHashable<H>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<H: Debug + Hash> Debug for DefaultHashable<H>

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

Formats the value using the given formatter.

impl<H: Hash + Hash> Hash for DefaultHashable<H>

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<H: Hash> Hashable for DefaultHashable<H>

type Hasher = KeyHasher

The hasher implementation used internally.

fn hashable(&self) -> u64

Generate the hash of this object.

impl<H: Ord + Hash> Ord for DefaultHashable<H>

fn cmp(&self, other: &DefaultHashable<H>) -> 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<H: PartialEq + Hash> PartialEq for DefaultHashable<H>

fn eq(&self, other: &DefaultHashable<H>) -> 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<H: PartialOrd + Hash> PartialOrd for DefaultHashable<H>

fn partial_cmp(&self, other: &DefaultHashable<H>) -> 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.
