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

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