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

👎 Deprecated since 0.6.0:

use WeightedIndex instead

Expand description

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

Deprecated: use WeightedIndex instead.

Implementations

source

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

source

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.
