Trait SampleRange

pub trait SampleRange<T> {
    // Required methods
    fn sample_single<R>(self, rng: &mut R) -> Result<T, Error>
       where R: RngCore + ?Sized;
    fn is_empty(&self) -> bool;
}

Range that supports generating a single sample efficiently.

Any type implementing this trait can be used to specify the sampled range for Rng::random_range.

Required Methods

fn sample_single<R>(self, rng: &mut R) -> Result<T, Error>

where R: RngCore + ?Sized,

Generate a sample from the given range.

fn is_empty(&self) -> bool

Check whether the range is empty.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
