module Athena::Routing::Requirement #

Includes types related to route requirements.

The namespace also exposes various regex constants representing common universal requirements to make using them in routes easier.

class ExampleController < ATH::Controller
  @[ARTA::Get(
    "/user/{id}",
    requirements: {
      "id" => ART::Requirement::DIGITS,
    }
  )]
  def get_user(id : Int64) : Int64
    id
  end

  @[ARTA::Get(
    "/article/{slug}",
    requirements: {
      "slug" => ART::Requirement::ASCII_SLUG,
    }
  )]
  def get_article(slug : String) : String
    slug
  end
