content_length | Returns the optional value of Content-Length if known.
content_length_remaining | Returns the remaining content length if known.
eager | Returns `true` if the eager parse option is set. — Set the eager parse option.

on_chunk_header | Set a callback to be invoked on each chunk header.

##### Template Parameters

Type | Description
--- | ---
`isRequest` | Indicates whether a request or response will be parsed.
`Body` | The type used to represent the body. This must meet the requirements of Body.
`Allocator` | The type of allocator used with the `basic_fields` container.

##### Remarks

A new instance of the parser is required for each message.
