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 bytes continuedz, N z []) DEFAULT_IS_TEXTgetr2 _data_reprlenr3r5joinfiltername)self expect_text data_repris_text data_typelength non_finalmetadatas& r__str__ Frame.__str__s**..t{{; !__. %0Bvh  N#5s499~/B(LM(((B 99VD9i*HIJ++""#1YKr(1==rcV^8dQhRR/#)r=r>ztuple[str, bool | None]r)r@s"rrArBsF"F"3F"rc VP'g(RVPPVP43#VP\Jd,\ \ PVP44R3#\VP4^VP,8d\VPR^VP,^,4p\VPRVP,^,R4p\VVP\8gR7;'d\VVPR7pV'd"\!W,P#RR74pMa\VP4p\VVP\8gVPR7pV'd\!VP#RR74pV'gVPp\V4VP^,8dCVP^,^, ^,pR P%VR^V,R Wg)R.4pR P%R V44p\X4VP8d8VP^,^, pVR^V,R ,WG)R,pWC3# \\3dELJi;i)z Return a human-readable representation of the payload.
