Struct `IntoChars`

#[must_use = "iterators are lazy and do nothing unless consumed"]
pub struct IntoChars { pub(in ::string) bytes: IntoIter<u8> }

An iterator over the chars of a string.

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

Fields

bytes: IntoIter<u8>

Implementations

`impl IntoChars`

fn as_str(&self) -> &str

Views the underlying data as a subslice of the original data.

Examples

#![feature(string_into_chars)]

let mut chars = String::from("abc").into_chars();

assert_eq!(chars.as_str(), "abc");
chars.next();
assert_eq!(chars.as_str(), "bc");
chars.next();
chars.next();
assert_eq!(chars.as_str(), "");

fn into_string(self) -> String

Consumes the IntoChars, returning the remaining string.

Examples

#![feature(string_into_chars)]

let chars = String::from("abc").into_chars();
assert_eq!(chars.into_string(), "abc");

let mut chars = String::from("def").into_chars();
chars.next();
assert_eq!(chars.into_string(), "ef");
