Function mz_repr::strconv::escape_elem

fn escape_elem<F, E>(buf: &mut F, start: usize)where
    F: FormatBuffer,
    E: ElementEscaper,

Escapes a list, record, or map element in place.

The element must start at start and extend to the end of the buffer. The buffer will be resized if escaping is necessary to account for the additional escape characters.

The needs_escaping function is used to determine whether an element needs to be escaped. It is provided with the bytes of each element and should return whether the element needs to be escaped.
