Examples

See also IntMap and IntSet for some easier usage examples.

use nohash_hasher::BuildNoHashHasher;
use std::collections::HashMap;

let mut m: HashMap::<u8, char, BuildNoHashHasher<u8>> =
    HashMap::with_capacity_and_hasher(2, BuildNoHashHasher::default());

m.insert(0, 'a');
m.insert(1, 'b');

assert_eq!(Some(&'a'), m.get(&0));
assert_eq!(Some(&'b'), m.get(&1));

struct BuildNoHashHasher<T>(/* private fields */);

Implementations

impl<H> BuildHasherDefault<H>

pub const fn new() -> BuildHasherDefault<H>

Creates a new BuildHasherDefault for Hasher H.

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) -> H

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) -> BuildHasherDefault<H>

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<(), Error>

Formats the value using the given formatter.

impl<H> Default for BuildHasherDefault<H>

fn default() -> BuildHasherDefault<H>

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.
