Struct flow_sdk::algorithms::rand::distributions::WeightedChoice

pub struct WeightedChoice<'a, T> where
    T: 'a,  { /* fields omitted */ }

👎 Deprecated since 0.6.0:

use WeightedIndex instead

A distribution that selects from a finite collection of weighted items.

Deprecated: use WeightedIndex instead.

Implementations

impl<'a, T> WeightedChoice<'a, T> where
    T: Clone, 

pub fn new(items: &'a mut [Weighted<T>]) -> WeightedChoice<'a, T>

👎 Deprecated since 0.6.0:

use WeightedIndex instead

Create a new WeightedChoice.

Panics if:

• items is empty
• the total weight is 0
• the total weight is larger than a u32 can contain.
