Struct BuildHasherDefault

pub struct BuildHasherDefault<H> { /* private fields */ }

A copy of core::hash::BuildHasherDefault, but with a const constructor.

This will eventually be deprecated once the version in core becomes const-constructible (presumably using const Default).

Trait Implementations

impl<H> BuildHasher for BuildHasherDefault<H>

where H: Default + Hasher,

type Hasher = H

Type of the hasher that will be created.

fn build_hasher(&self) -> Self::Hasher

Creates a new hasher.

fn hash_one<T>(&self, x: T) -> u64

where T: Hash, Self: Sized, Self::Hasher: Hasher,

Calculates the hash of a single value.

impl<H> Clone for BuildHasherDefault<H>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<H> Debug for BuildHasherDefault<H>

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

Formats the value using the given formatter.

impl<H> Default for BuildHasherDefault<H>

fn default() -> Self

Returns the “default value” for a type.

impl<H> PartialEq for BuildHasherDefault<H>

fn eq(&self, _other: &BuildHasherDefault<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.

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.
