Fields

An instance of [*Fields] is a container for holding HTTP header fields and their values. The implementation also calls upon the container to store the request target and non-standard strings for method and obsolete reason phrase as needed. Types which meet these requirements can always be serialized.

Associated Types

* [link beast.ref.boost__beast__http__is_fields `is_fields`]
* __FieldsWriter__

Requirements

In this table:

* `F` denotes a type that meets the requirements of [*Fields].
* `W` denotes a type meeting the requirements of __FieldsWriter__.
* `a` denotes a value of type `F`.
* `c` denotes a (possibly const) value of type `F`.
* `b` is a value of type `bool`
* `n` is a value of type `boost::optional<std::uint64_t>`.
* `s` is a value of type [link beast.ref.boost__beast__string_view `string_view`].
* `v` is a value of type `unsigned int` representing the HTTP-version.

`F::writer`

`W`

A type which meets the requirements of __FieldsWriter__.

`c.get_method_impl()`

`string_view`

Returns the method text. The implementation only calls this function for request headers when retrieving the method text previously set with a call to `set_method_impl` using a non-empty string.

`c.get_target_impl()`

Returns the target string. The implementation only calls this function for request headers.

`c.get_reason_impl()`
