  module Plugins
    # The async_thread_pool plugin makes it slightly easier to use the async_thread_pool
    # Database extension with models.  It makes Model.async return an async dataset for the
    # model, and support async behavior for #destroy, #with_pk, and #with_pk! for model
    # datasets:
    #
    #   # Will load the artist with primary key 1 asynchronously
    #   artist = Artist.async.with_pk(1)
    #
    # You must load the async_thread_pool Database extension into the Database object the
    # model class uses in order for async behavior to work.
    #
    # Usage:
    #
    #   # Make all model subclass datasets support support async class methods and additional
    #   # async dataset methods
    #   Sequel::Model.plugin :async_thread_pool
    #
    #   # Make the Album class support async class method and additional async dataset methods
    #   Album.plugin :async_thread_pool
