Struct TruncatedNormal

pub struct TruncatedNormal<F>
where
    StandardNormal: Distribution<F>,
{ /* private fields */ }

A truncated normal distribution is similar to a normal distribution, however, any generated value over two standard deviations from the mean is discarded and re-generated.

impl<F: Ord> Ord for TruncatedNormal<F>

where StandardNormal: Distribution<F>,

fn cmp(&self, other: &TruncatedNormal<F>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self
