Struct HasherRng

pub struct HasherRng<H = RandomState> { /* private fields */ }

Available on crate feature util only.

A Rng implementation that uses a Hasher to generate the random values. The implementation uses an internal counter to pass to the hasher for each iteration of Rng::next_u64.

Default

This hasher has a default type of RandomState which just uses the libstd method of getting a random u64.

Implementations

impl HasherRng

pub fn new() -> Self

Create a new default HasherRng.

impl<H> HasherRng<H>

pub fn with_hasher(hasher: H) -> Self

Create a new HasherRng with the provided hasher.

Trait Implementations

impl<H: Clone> Clone for HasherRng<H>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<H: Debug> Debug for HasherRng<H>

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

Formats the value using the given formatter.

impl Default for HasherRng

fn default() -> Self

Returns the “default value” for a type.

impl<H> Rng for HasherRng<H>

where H: BuildHasher,

fn next_u64(&mut self) -> u64

Generate a random u64.

fn next_f64(&mut self) -> f64

Generate a random f64 between [0, 1).

fn next_range(&mut self, range: Range<u64>) -> u64

Randomly pick a value within the range.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
