owned-chars

Travis CI

This crate provides an extension trait for String with two methods, into_chars and into_char_indices. These methods parallel String::chars and String::char_indices, but the iterators they create consume the String instead of borrowing it.

Release notes

  • 0.3.0
    • Rewrite to use delegate crate
    • Fix/breaking change: OwnedChars::as_str works the same way as std::Chars::as_str

Example

use owned_chars::OwnedChars;

fn main() {
    let mut chars = OwnedChars::from_string("0123456789ABCDEF".to_owned());
    let next_is_digit = |chars: &mut OwnedChars| chars.next().map_or(false, |c| c.is_numeric());

    assert!(next_is_digit(&mut chars)); // 0
    assert!(next_is_digit(&mut chars)); // 1
    assert!(next_is_digit(&mut chars)); // 2
    assert!(next_is_digit(&mut chars)); // 3
    assert!(next_is_digit(&mut chars)); // 4
    assert!(next_is_digit(&mut chars)); // 5
    assert!(next_is_digit(&mut chars)); // 6
    assert!(next_is_digit(&mut chars)); // 7
    assert!(next_is_digit(&mut chars)); // 8
    assert!(next_is_digit(&mut chars)); // 9

    assert!(!next_is_digit(&mut chars)); // A
    assert!(!next_is_digit(&mut chars)); // B
    assert!(!next_is_digit(&mut chars)); // C
    assert!(!next_is_digit(&mut chars)); // D
    assert!(!next_is_digit(&mut chars)); // E
    assert!(!next_is_digit(&mut chars)); // F
}
