write_last_chunk :: (out: *[..] u8) -> boolThe zero-size chunk with optional trailers, which ends a chunked body. False, with nothing written, when a trailer is not valid or is a field a trailer may not be (framing, Host). Appends the zero-size chunk that ends a chunked body, with no trailers. Returns true.
Parameters
- out: *[..] u8
Returns
- bool
write_last_chunk :: (out: *[..] u8, trailers: [] Header_Field) -> boolAppends the zero-size chunk that ends a chunked body, followed by trailers. Returns false and writes nothing when a trailer
is not a valid field, or is one a trailer may not be (Content-Length, Transfer-Encoding, Host).
Parameters
- out: *[..] u8
- trailers: [] Header_Field
Returns
- bool
