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:

http/status.cr
