Trait ndarray_rand::rand_distr::weighted_alias::AliasableWeight[][src]

pub trait AliasableWeight: Copy + SampleUniform + PartialOrd<Self> + Add<Self, Output = Self> + AddAssign<Self> + Sub<Self, Output = Self> + SubAssign<Self> + Mul<Self, Output = Self> + MulAssign<Self> + Div<Self, Output = Self> + DivAssign<Self> + Sum<Self> {
    pub const MAX: Self;
    pub const ZERO: Self;

    pub fn try_from_u32_lossy(n: u32) -> Option<Self>;

    pub fn sum(values: &[Self]) -> Self { ... }
}

Trait that must be implemented for weights, that are used with WeightedAliasIndex. Currently no guarantees on the correctness of WeightedAliasIndex are given for custom implementations of this trait.

Associated Constants

pub const MAX: Self[src]

Maximum number representable by Self.

pub const ZERO: Self[src]

Element of Self equivalent to 0.

Required methods

pub fn try_from_u32_lossy(n: u32) -> Option<Self>[src]

Produce an instance of Self from a u32 value, or return None if out of range. Loss of precision (where Self is a floating point type) is acceptable.
