type: paragraph
The standard library provides the type `std::ostream` for performing high level write operations on character streams. The variable `std::cout` is based on this output stream. This example uses the buffer oriented interface of __serializer__ to write an HTTP message to a `std::ostream`:

Buffer-Oriented Serializing
Buffer-Oriented Serializing
An instance of __serializer__ can be invoked directly, without using the provided stream operations. This could be useful for implementing algorithms on objects whose interface does not conform to __Stream__. For example, a [@https://github.com/libuv/libuv *libuv* socket]. The serializer interface is interactive; the caller invokes it repeatedly to produce buffers until all of the serialized octets have been generated. Then the serializer is destroyed.

The serializer interface is interactive; the caller invokes it repeatedly to produce buffers until all of the serialized octets have been generated. Then the serializer is destroyed.
To obtain the serialized next buffer sequence, call [link beast.ref.boost__beast__http__serializer.next `serializer::next`]. Then, call [link beast.ref.boost__beast__http__serializer.consume `serializer::consume`] to indicate the number of bytes consumed. This updates the next set of buffers to be returned, if any. `serializer::next` takes an error code parameter and invokes a visitor argument with the error code and buffer of unspecified type. In C++14 this is easily expressed with a generic lambda. The function [link beast.ref.boost__beast__http__serializer.is_done `serializer::is_done`] will return `true` when all the buffers have been produced. This C++14 example prints the buffers to standard output:

Split Serialization
Split Serialization
In some cases, such as the handling of the [@https://tools.ietf.org/html/rfc7231#section-5.1.1 Expect: 100-continue] field, it may be desired to first serialize the header, perform some other action, and then continue with serialization of the body. This is accomplished by calling [link beast.ref.boost__beast__http__serializer.split `serializer::split`] with a boolean indicating that when buffers are produced, the last buffer containing serialized header octets will not contain any octets corresponding to the body. The function [link beast.ref.boost__beast__http__serializer.is_header_done `serializer::is_header_done`] informs the caller whether the header been serialized fully. In this C++14 example we print the header first, followed by the body:
