pub fn stamp_error_ids_in_bytes<'a>(body: &'a [u8], id: &str) -> Cow<'a, [u8]>Expand description
Byte-oriented stamp_error_ids: parse body as JSON, stamp missing
errors[].id with id, and re-serialize.
Returns the input unchanged (a borrowed Cow) when
the body is not JSON, is not an errors document, or already carries an id
on every member — so it is a safe no-op on non-error and non-JSON bodies.
