1.6.0[][src]Struct std::vec::Drain

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

A draining iterator for Vec<T>.

This struct is created by the drain method on Vec.

Methods

impl<'a, T> Drain<'a, T>[src]

Important traits for &'_ [u8]
pub fn as_slice(&self) -> &[T][src]

🔬 This is a nightly-only experimental API. (vec_drain_as_slice #58957)

recently added

Returns the remaining items of this iterator as a slice.

Examples

let mut vec = vec!['a', 'b', 'c'];
let mut drain = vec.drain(..);
assert_eq!(drain.as_slice(), &['a', 'b', 'c']);
let _ = drain.next().unwrap();
assert_eq!(drain.as_slice(), &['b', 'c']);Run
