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