Enum hyper::http::h1::HttpReader [−][src]
pub enum HttpReader<R> { SizedReader(R, u64), ChunkedReader(R, Option<u64>), EofReader(R), EmptyReader(R), }
Readers to handle different Transfer-Encodings.
If a message body does not include a Transfer-Encoding, it should include a Content-Length header.
Variants
SizedReader(R, u64)
A Reader used when a Content-Length header is passed with a positive integer.
ChunkedReader(R, Option<u64>)
A Reader used when Transfer-Encoding is chunked
.
EofReader(R)
A Reader used for responses that don't indicate a length or chunked.
Note: This should only used for Response
s. It is illegal for a
Request
to be made with both Content-Length
and
Transfer-Encoding: chunked
missing, as explained from the spec:
If a Transfer-Encoding header field is present in a response and the chunked transfer coding is not the final encoding, the message body length is determined by reading the connection until it is closed by the server. If a Transfer-Encoding header field is present in a request and the chunked transfer coding is not the final encoding, the message body length cannot be determined reliably; the server MUST respond with the 400 (Bad Request) status code and then close the connection.
EmptyReader(R)
A Reader used for messages that should never have a body.
