}Expand description
Trait representing a streaming body of a Request or Response.
Individual frames are streamed via the poll_frame function, which asynchronously yields
instances of Frame<Data>.
Frames can contain a data buffer of type Self::Data. Frames can also contain an optional
set of trailers used to finalize the request/response exchange. This is mostly used when using
the HTTP/2.0 protocol.
The size_hint function provides insight into the total number of bytes that will be streamed.

fn is_end_stream(&self) -> bool
fn is_end_stream(&self) -> bool
Returns true when the end of stream has been reached.
An end of stream means that poll_frame will return None.
A return value of false does not guarantee that a value will be
returned from poll_frame.
