Struct std::string::Drain1.6.0[][src]

pub struct Drain<'a> { /* fields omitted */ }

A draining iterator for String.

This struct is created by the drain method on String. See its documentation for more.


impl<'a> Drain<'a>[src]

pub fn as_str(&self) -> &str[src]

🔬 This is a nightly-only experimental API. (string_drain_as_str #76905)

Returns the remaining (sub)string of this iterator as a slice.


let mut s = String::from("abc");
let mut drain = s.drain(..);
assert_eq!(drain.as_str(), "abc");
let _ =;
assert_eq!(drain.as_str(), "bc");
