Expand description

Indicates a format which contains characters from Unicode (all of it, or some proper subset).

Required Associated Types§

source

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

Iterator for characters and their byte indices.

Required Methods§

source

unsafe fn char_indices(buf: &'a [u8]) -> Self::Iter

Iterate over the characters of the string and their byte indices.

You may assume the buffer is already validated for Format.

source

fn encode_char<F>(ch: char, cont: F) -> Result<(), ()>
where F: FnOnce(&[u8]),

Encode the character as bytes and pass them to a continuation.

Returns Err(()) iff the character cannot be represented.

Object Safety§

This trait is not object safe.
