    enum error

##### Values

Name | Description
--- | ---
`end_of_stream` | The end of the stream was reached. This error is returned when attempting to read HTTP data, and the stream returns the error boost::asio::error::eof before any octets corresponding to a new HTTP message have been received.
`partial_message` | The incoming message is incomplete. This happens when the end of stream is reached during parsing and some octets have been received, but not the entire message.
`need_more` | Additional buffers are required. This error is returned during parsing when additional octets are needed. The caller should append more data to the existing buffer and retry the parse operaetion.
`unexpected_body` | An unexpected body was encountered during parsing. This error is returned when attempting to parse body octets into a message container which has the empty_body body type.empty_body
`need_buffer` | Additional buffers are required. This error is returned under the following conditions:During serialization when using buffer_body. The caller should update the body to point to a new buffer or indicate that there are no more octets in the body. During parsing when using buffer_body. The caller should update the body to point to a new storage area to receive additional body octets.
`end_of_chunk` | The end of a chunk was reached.
`buffer_overflow` | Buffer maximum exceeded. This error is returned when reading HTTP content into a dynamic buffer, and the operation would exceed the maximum size of the buffer.
`header_limit` | Header limit exceeded. The parser detected an incoming message header which exceeded a configured limit.
`body_limit` | Body limit exceeded. The parser detected an incoming message body which exceeded a configured limit.
`bad_alloc` | A memory allocation failed. When basic_fields throws std::bad_alloc, it is converted into this error by parser.
`bad_line_ending` | The line ending was malformed.
`bad_method` | The method is invalid.
`bad_target` | The request-target is invalid.
`bad_version` | The HTTP-version is invalid.
`bad_status` | The status-code is invalid.
`bad_reason` | The reason-phrase is invalid.
`bad_field` | The field name is invalid.
`bad_value` | The field value is invalid.
`bad_content_length` | The Content-Length is invalid.
`bad_transfer_encoding` | The Transfer-Encoding is invalid.
`bad_chunk` | The chunk syntax is invalid.
`bad_chunk_extension` | The chunk extension is invalid.
`bad_obs_fold` | An obs-fold exceeded an internal limit.
