Expand description

The pallet module in each FRAME pallet hosts the most important items needed to construct this pallet.

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.


  • pub use __tt_error_token_1 as tt_error_token;
  • pub use __tt_default_parts_7 as tt_default_parts;
  • pub use __tt_extra_parts_7 as tt_extra_parts;
  • pub use __tt_default_parts_v2_7 as tt_default_parts_v2;


  • Auto-generated docs-only module listing all defined dispatchables for this pallet.
  • Auto-generated docs-only module listing all (public and private) defined storage types for this pallet.



  • Contains a variant per dispatchable extrinsic that this pallet has.
  • The Error enum of this pallet.


  • Configuration trait of this pallet.

Type Aliases§

  • Current epoch authorities.
  • Current slot number.
  • Current epoch index.
  • The block numbers when the last and current epoch have started, respectively N-1 and N. NOTE: We track this is in order to annotate the block number when a given pool of entropy was fixed (i.e. it was known to chain observers). Since epochs are defined in slots, which may be skipped, the block numbers may not line up with the slot numbers.
  • The slot at which the first epoch actually started. This is 0 until the first block of the chain.
  • ModuleDeprecated
    Type alias to Pallet, to be used by construct_runtime.
  • The epoch randomness for the current epoch.
