Class: Async::Discord::Api::PathTree

Inherits:
Matrix::Api::PathTree show all
Defined in:
lib/async/discord/api/path_tree.rb

Overview

Loads the Discord HTTP API OpenAPI spec and builds a PathTree trie of all valid endpoints. Reuses the core Node/insert/match logic from Async::Matrix::Api::PathTree.

The Discord spec is a single JSON file (OpenAPI 3.1.0) with the server URL discord.com/api/v10, yielding prefix segments [“api”, “v10”].

tree = PathTree.load
tree.match(%w[api v10 channels 123 messages], "POST")
# => { valid: true, operation_id: "create_message", methods: ["post"] }
