# Struct collections::vec::Drain 1.6.0 [−] [src]

    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`.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
