Struct Chars

pub struct Chars<'a> { /* private fields */ }

Const equivalent of core::str::Chars

Implementations

impl<'a> Chars<'a>

pub const fn copy(&self) -> Self

Creates a clone of this iterator

pub const fn rev(self) -> RChars<'a>

Reverses the iterator

pub const fn next(self) -> Option<(char, Self)>

Advances the iterator and returns the next value.

pub const fn next_back(self) -> Option<(char, Self)>

Removes and returns an element from the end of the iterator.

pub const fn as_str(&self) -> &'a str

Gets a string slice to the yet-to-be-iterated characters.

Example

use konst::{for_range, option, string};

const S: &str = {
    let mut iter = string::chars("hello world");
    for_range!{_ in 0..6 =>
        (_, iter) = option::unwrap!(iter.next());
    }
    iter.as_str()
};

assert_eq!(S, "world")
