Struct sample_std::VecSampler

pub struct VecSampler<S, I> {
    pub length: S,
    pub el: I,
}

Sample a Vec with a length drawn from a usize Sample and elements drawn from the el sampler.

Shrinking attempts to first shrink the length, and then shrink each element within the Vec.

Fields

length: S

el: I

Trait Implementations

impl<S: Clone, I: Clone> Clone for VecSampler<S, I>

fn clone(&self) -> VecSampler<S, I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug, I: Debug> Debug for VecSampler<S, I>

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

Formats the value using the given formatter.

impl<S, I, T> Sample for VecSampler<S, I>where S: Sample<Output = usize>, I: Sample<Output = T>, T: Clone + 'static,

type Output = Vec<T, Global>

fn generate(&self, g: &mut Random) -> Self::Output

Randomly generate the requested type.

fn shrink(&self, v: Self::Output) -> Shrunk<'_, Self::Output>

Shrink the given value into a “smaller” value. Defaults to an empty iterator (which represents that the value cannot be shrunk).

fn try_convert<T, I, F>(self, from: F, try_into: I) -> TryConvert<Self, F, I>where Self: Sized, F: Fn(Self::Output) -> T + Copy, I: Fn(T) -> Option<Self::Output>,

Convert this sampler into a new sampler with from and try_into functions:

fn zip<OS>(self, other: OS) -> Zip<Self, OS>where Self: Sized, OS: Sample,

“Zip” two samplers together. Functionally equivalent to (self, other).

fn chain_resample<F, RS>( self, transform: F, subsamples: usize ) -> ChainResample<Self, F>where Self: Sized, F: Fn(Self::Output) -> RS, RS: Sample,

“Resampling” method for chaining samplers.
