Struct wgpu_core::hash_utils::PreHashedKey

pub struct PreHashedKey<K>(u64, PhantomData<fn() -> K>);

A pre-hashed key using FxHash which allows the hashing operation to be disconnected from the storage in the map.

Tuple Fields

0: u64

1: PhantomData<fn() -> K>

Implementations

impl<K: Hash> PreHashedKey<K>

pub fn from_key(key: &K) -> Self

Trait Implementations

impl<K> Clone for PreHashedKey<K>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K> Debug for PreHashedKey<K>

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

Formats the value using the given formatter.

impl<K> Hash for PreHashedKey<K>

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<K> PartialEq for PreHashedKey<K>

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

This method tests for self and other values to be equal, and is used by ==.

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

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