The main components of this pallet are:

  • Pallet, which implements all of the dispatchable extrinsics of the pallet, among other public functions.
    • The subset of the functions that are dispatchable can be identified either in the dispatchables module or in the Call enum.
  • storage_types, which contains the list of all types that are representing a storage item. Otherwise, all storage items are listed among Type Definitions.
  • Config, which contains the configuration trait of this pallet.
  • Event and Error, which are listed among the Enums.
