42 * http::request provides the following functionality for working with HTTP
45 * - Initialize request via manually setting each element
46 * - Initialize request via reading raw bytes and parsing
47 * - Once initialized, access individual parsed elements
48 * - Once initialized, read entire request as raw bytes

61 * Process up to len bytes from input buffer buf. Returns the number of
62 * bytes processed. Bytes left unprocessed means bytes left over after the
63 * final header delimiters.
65 * Consume is a streaming processor. It may be called multiple times on one
66 * request and the full headers need not be available before processing can
67 * begin. If the end of the request was reached during this call to consume
68 * the ready flag will be set. Further calls to consume once ready will be

72 * error reasons include malformed requests, incomplete requests, and max
