# enum HTTP::Status

##
Overview

An enum that provides additional support around HTTP status codes.

Based on Hypertext Transfer Protocol (HTTP) Status Code Registry

It provides constants for the defined HTTP status codes as well as helper methods to easily identify the type of response.

NOTE To use `Status`, you must explicitly import it with `require "http/status"`

##
Defined in:
