Struct rand::distributions::uniform::UniformChar

pub struct UniformChar { /* private fields */ }

The back-end implementing UniformSampler for char.

Unless you are implementing UniformSampler for your own type, this type should not be used directly, use Uniform instead.

This differs from integer range sampling since the range 0xD800..=0xDFFF are used for surrogate pairs in UCS and UTF-16, and consequently are not valid Unicode code points. We must therefore avoid sampling values in this range.

Trait Implementations

impl Clone for UniformChar

fn clone(&self) -> UniformChar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UniformChar

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

Formats the value using the given formatter.

impl UniformSampler for UniformChar

type X = char

The type sampled by this implementation.

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

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) -> Self

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) -> Self::X

Sample a value.

fn sample_single<R: Rng + ?Sized, B1, B2>( low: B1, high: B2, rng: &mut R ) -> Self::X

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: B1, high: B2, rng: &mut R ) -> Self::X

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].
