Sometimes it is necessary to first send or receive the HTTP header. For example, to read the header and take action before continuing to read the body. These functions use a __parser__ or __serializer__ to read or write the header: [link beast.ref.boost__beast__http__read_header.overload2 `read_header`], [link beast.ref.boost__beast__http__write_header.overload2 `write_header`], [link beast.ref.boost__beast__http__async_read_header `async_read_header`], and [link beast.ref.boost__beast__http__async_write_header `async_write_header`].

* [issue 2915] Removed mutating operations in initiating functions
* [issue 2915] Fixed cancellation handling in `teardown_tcp_op`
* [issue 2920] Set `state_` in `basic_parser` before calling `on_finish_impl`
* [issue 2939] Removed static specifier from `clamp` functions

The design of the message container in this library is cumbersome with its system of customization using trait specializations. The use of these customizations is extremely limited due to the way they are used in the container declaration, making the design overly complex without corresponding benefit.

The implementation calls this constructor to indicate that the fields being serialized form part of a chunked encoding final-chunk trailer. The lifetime of `f` is guaranteed to end no earlier than after the `W` is destroyed.

Returns the obsolete request text. The implementation only calls this for response headers when retrieving the reason text previously set with a call to `set_reason_impl` using a non-empty string.

The standard library provides the type `std::istream` for performing high level read operations on character streams. The variable `std::cin` is based on this input stream. This example uses the buffer oriented interface of __basic_parser__ to build a stream operation which parses an HTTP message from a `std::istream`:

This class wraps the underlying memory of an existing buffer sequence and presents a suffix of the original sequence. The length of the suffix may be progressively shortened. This lets callers work with sequential increments of a buffer sequence.

In this example, the server reads the initial HTTP request header into a dynamic buffer, then later uses the buffered data to attempt a websocket upgrade.

This function is called by the implementation to determine the maximum number of allowed bytes to be transferred in the next write operation. The actual number of bytes subsequently transferred may be less than this number.

If the policy returns a value of zero, the read operation will asynchronously wait until the next timer interval before retrying. When the retry occurs, this function will be called again.

Called to ask the generator to produce buffers containing data for processing.

The returned value is the __ConstBufferSequence__ representing unconsumed data.

The function will ensure that `ec.failed()` is `false` if there was no error or set to the appropriate error code if there was one.

If no unconsumed data is available, this operation shall make progress to eventually reach completion.

The result of invoking `prepare` after completion or encountered error(s) is defined by the generator implementation. It can not be assumed to be meaningful or safe to do so, in general.

The capacity of the buffer returned is defined by the generator implementation.

[*Note:] Any buffers obtained by previous calls to `prepare` are invalidated.

If no data or control frames are received from the peer for a time equal to the idle timeout, then the connection will time out. The value returned by [link beast.ref.boost__beast__websocket__stream_base.none `stream_base::none()`] may be assigned to disable this timeout.

When a timeout is set, it cancels any previous read or write timeout for which no outstanding operation is in progress. Algorithms which loop over logical operations simply need to set the timeout once before the logical operation, it is not necessary to call `expires_never` in this case. Here we implement an algorithm which continuously echoes lines back, with a timeout. This example is implemented as a complete function.
