Trait quasirandom::FromUniform

source · [−]
pub trait FromUniform {
    fn from_uniform(uniform_value: f64) -> Self;
}
Expand description

A type that implements FromUniform is able to instantiate itself from an f64 uniformly distributed in the range [0, 1).

For example, bool maps values < 0.5 to false and >= 0.5 to true, and u32 maps values evenly in 0..=u32::MAX.

The mapping is less clear when it comes to more complicated enums, such as Option. In general, this is up to the judgment of the implementer. Reasonable implementations are provided for many common standard library types.
