[−][src]Struct rand::distributions::WeightedChoice
Deprecated since 0.6.0:
use WeightedIndex instead
A distribution that selects from a finite collection of weighted items.
Deprecated: use WeightedIndex
instead.
Methods
impl<'a, T: Clone> WeightedChoice<'a, T>
[src]
pub fn new(items: &'a mut [Weighted<T>]) -> WeightedChoice<'a, T>
[src]
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.
