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.

Re-exports

  • 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;

Modules

  • Default implementations of DefaultConfig, which can be used to implement Config.
  • 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.

Structs

  • Can be used to configure the genesis state of this pallet.
  • The Pallet struct, the main type that implements traits and standalone functions within the pallet.

Enums

  • Contains a variant per dispatchable extrinsic that this pallet has.
  • Error for the System pallet
  • Event for the System pallet.

Traits

Type Aliases

  • The full account information for a particular account ID.
  • Map of block numbers to block hashes.
  • Stores the spec_version and spec_name of when the last runtime upgrade happened.
  • ModuleDeprecated
    Type alias to Pallet, to be used by construct_runtime.
