Trait SampleLen 

pub trait SampleLen: Sample<Output = ArrayRef> + SetLen { }

Trait Implementations

impl Sample for Box<dyn SampleLen>

type Output = Arc<dyn Array>

fn generate(&mut 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, 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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
