This function is intended for logging and debugging. It doesn't aim to support round-tripping because payloads can be too long for displaying conveniently. Instead, it shows the beginning and the end. It's robust to incorrect data. It attempts to decode UTF-8 payloads whenever possible, even for binary frames and control frames, because those frequently contain UTF-8 data. It applies the same logic to continuation frames, because we don't know if they continue a text frame or a binary frame. textbinaryz byters continuedz, N z []) DEFAULT_IS_TEXTgetr= _data_reprlenr>r@joinfiltername)self expect_text data_repris_text data_typelength non_finalmetadatas r)__str__z Frame.__str__s*..t{;; !__.. 7%00BB7Vvvh  NNMMs49~~/B/BMM(3BB 99VD9fi*HIIJJ+"==Y==(====r(tuple[str, bool | None]c|js!d|j|jfS|jturF t t |jdfS#ttf$rYnwxYwt|jd|j zkrt|jdd|j zdz}t|jd|j zdzd}t||jtkot||j }|r&t!||zd }n^t|j}t||jtk|j }|r#t!|d }|s}|j}t||j dzkr<|j dzd z dz}d|dd|zd|| dg}dd|D}t||j kr)|j dzd z }|dd|zdz|| dz}||fS)z Return a human-readable representation of the payload.
