[][src]Struct alloc::vec::DrainFilter

pub struct DrainFilter<'a, T, F, A: Allocator = Global> where
    F: FnMut(&mut T) -> bool, 
{ /* fields omitted */ }
🔬 This is a nightly-only experimental API. (drain_filter #43244)

recently added

An iterator which uses a closure to determine if an element should be removed.

This struct is created by Vec::drain_filter. See its documentation for more.

Example

#![feature(drain_filter)]

let mut v = vec![0, 1, 2];
let iter: std::vec::DrainFilter<_, _> = v.drain_filter(|x| *x % 2 == 0);
