Struct CharIndices

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

Const equivalent of core::str::CharIndices

Implementations

impl<'a> CharIndices<'a>

pub const fn copy(&self) -> Self

Creates a clone of this iterator

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

Reverses the iterator

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

Advances the iterator and returns the next value.

pub const fn next_back(self) -> Option<((usize, 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::char_indices("this is fine");
    for_range!{_ in 0..8 =>
        (_, iter) = option::unwrap!(iter.next());
    }
    iter.as_str()
};

assert_eq!(S, "fine")

Trait Implementations

impl ConstIntoIter for CharIndices<'_>

type Kind = IsIteratorKind

What kind of type this is:

type IntoIter = CharIndices<'_>

The iterator that this can be converted into.

type Item = (usize, char)

The item that Self::IntoIter yields on .next()
