New classes:
class async_completion:
Helper class for implementing asynchronous initiation functions.
See n3964:
Library Foundations for Asynchronous Operations, Revision 1
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n3964.pdf
class basic_streambuf:
Meets the requirements of Streambuf.
class buffered_readstream:
Buffers a ReadStream with a ConstBufferSequence.
class consuming_buffers:
Adapts a BufferSequence which wraps the underlying buffer
sequence and presents fewer bytes, with the retained bytes
occurring at the end of the sequence.
class handler_alloc:
A C++ Allocator the uses asio handler allocation hooks.
class static_streambuf:
An implementation of the Streambuf concept that uses a
fixed size buffer with size determined at compile-time.
class streambuf_readstream:
Buffers a ReadStream with a Streambuf.
New functions:
append_buffers()
Returns a new BufferSequence which efficiently concatenates
two or more buffer sequences together.
prepare_buffers()
Shortens a buffer sequence. The bytes excluded are at the
end of the underlying buffer sequence.
boost::asio::read_until()
A copy of boost::asio::read_until overloads, modified to work
with a beast::asio::basic_streambuf.
Debugging:
buffers_to_string()
Convert a ConstBufferSequence to a human readable string
suitable for diagnostics.
type_check.h:
Metafunctions for checking asio concepts:
AsyncReadStream, AsyncWriteStream
SyncReadStream, SyncWriteStream
ConstBufferSequence, MutableBufferSequence
Streambuf
Handler
Changes:
* All symbols moved up a namespace level.
* streambuf provides all move and copy special members,
behavior of moved from objects is well-defined.
Fixes:
* Fix basic_streambuf iterator category.
