## Streaming request
*HttpRequest* is a stream of `Bytes` objects. It could be used to read request
body payload. At the same time actix uses
[*Payload*](../actix_web/payload/struct.Payload.html) object.
*HttpRequest* provides several methods, which can be used for
payload access.At the same time *Payload* implements *Stream* trait, so it
could be used with various stream combinators. Also *Payload* provides
several convenience methods that return future object that resolve to Bytes object.
* *readexactly()* method returns *Future* that resolves when specified number of bytes
get received.
* *readline()* method returns *Future* that resolves when `\n` get received.
* *readuntil()* method returns *Future* that resolves when specified bytes string
matches in input bytes stream
body payload.
In this example handle reads request payload chunk by chunk and prints every chunk.
