All of the stream operations at higher levels thus far have operated on a complete header or message. At this level it is possible to send and receive messages incrementally. This allows resource constrained implementations to perform work bounded on storage, or allows better control when setting timeouts for example. These functions read or write bounded amounts of data and return the number of bytes transacted: [link beast.ref.boost__beast__http__read_some.overload2 `read_some`], [link beast.ref.boost__beast__http__write_some.overload2 `write_some`], [link beast.ref.boost__beast__http__async_read_some `async_read_some`], and [link beast.ref.boost__beast__http__async_write_some `async_write_some`].
