Struct alloc::slice::Split1.0.0[][src]

pub struct Split<'a, T, P> where
    T: 'a,
    P: FnMut(&T) -> bool, 
{ /* fields omitted */ }
Expand description

An iterator over subslices separated by elements that match a predicate function.

This struct is created by the split method on slices.

Example

let slice = [10, 40, 33, 20];
let mut iter = slice.split(|num| num % 3 == 0);
