Trait unicode_bidi::TextSource

pub trait TextSource<'text>: Sealed {
    type CharIter: Iterator<Item = char>;
    type CharIndexIter: Iterator<Item = (usize, char)>;
    type IndexLenIter: Iterator<Item = (usize, usize)>;
}

Trait that abstracts over a text source for use by the bidi algorithms. We implement this for str (UTF-8) and for u16 (UTF-16, native-endian). (For internal unicode-bidi use; API may be unstable.) This trait is sealed and cannot be implemented for types outside this crate.

Required Associated Types

type CharIter: Iterator<Item = char>

type CharIndexIter: Iterator<Item = (usize, char)>

type IndexLenIter: Iterator<Item = (usize, usize)>

Object Safety

This trait is not object safe.
