Struct DefaultHasher

pub struct DefaultHasher(/* private fields */);

The default Hasher used by RandomState.

The internal algorithm is not specified, and so it and its hashes should not be relied upon over releases.

Implementations

impl DefaultHasher

pub fn new() -> DefaultHasher

Creates a new DefaultHasher.

This hasher is not guaranteed to be the same as all other DefaultHasher instances, but is the same as all other DefaultHasher instances created through new or default.

Trait Implementations

impl Arbitrary for DefaultHasher

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = LazyJust<DefaultHasher, fn() -> DefaultHasher>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _args: <DefaultHasher as Arbitrary>::Parameters, ) -> <DefaultHasher as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for DefaultHasher

fn clone(&self) -> DefaultHasher

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DefaultHasher

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

Formats the value using the given formatter.

impl Default for DefaultHasher

fn default() -> DefaultHasher

Creates a new DefaultHasher using new. See its documentation for more.

impl Hasher for DefaultHasher

🔬This is a nightly-only experimental API. (hasher_prefixfree_extras)

Writes a length prefix into this hasher, as part of being prefix-free.
