Struct UniformUsize 

pub struct UniformUsize { /* private fields */ }

Available on 32-bit or 64-bit only.

The back-end implementing UniformSampler for usize.

Implementation notes

Sampling a usize value is usually used in relation to the length of an array or other memory structure, thus it is reasonable to assume that the vast majority of use-cases will have a maximum size under u32::MAX. In part to optimise for this use-case, but mostly to ensure that results are portable across 32-bit and 64-bit architectures (as far as is possible), this implementation will use 32-bit sampling when possible.

Trait Implementations

impl Clone for UniformUsize

fn clone(&self) -> UniformUsize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UniformUsize

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

Formats the value using the given formatter.

impl PartialEq for UniformUsize

fn eq(&self, other: &UniformUsize) -> 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.

impl UniformSampler for UniformUsize

type X = usize

The type sampled by this implementation.

fn new<B1, B2>(low_b: B1, high_b: B2) -> Result<Self, Error>

where B1: SampleBorrow<Self::X> + Sized, B2: SampleBorrow<Self::X> + Sized,

Construct self, with inclusive lower bound and exclusive upper bound [low, high).

fn new_inclusive<B1, B2>(low_b: B1, high_b: B2) -> Result<Self, Error>

where B1: SampleBorrow<Self::X> + Sized, B2: SampleBorrow<Self::X> + Sized,

Construct self, with inclusive bounds [low, high].

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> usize

Sample a value.

fn sample_single<R: Rng + ?Sized, B1, B2>( low_b: B1, high_b: B2, rng: &mut R, ) -> Result<Self::X, Error>

where B1: SampleBorrow<Self::X> + Sized, B2: SampleBorrow<Self::X> + Sized,

Sample a single value uniformly from a range with inclusive lower bound and exclusive upper bound [low, high).

fn sample_single_inclusive<R: Rng + ?Sized, B1, B2>( low_b: B1, high_b: B2, rng: &mut R, ) -> Result<Self::X, Error>

where B1: SampleBorrow<Self::X> + Sized, B2: SampleBorrow<Self::X> + Sized,

Sample a single value uniformly from a range with inclusive lower bound and inclusive upper bound [low, high].

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.
