Module frame::prelude::frame_system::pallet

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.

Modules

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

Structs

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

Enums

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

Traits

• Config
  Configuration trait of this pallet.
• DefaultConfig
  Based on Config. Auto-generated by #[pallet::config(with_default)]. Can be used in tandem with #[register_default_config] and #[derive_impl] to derive test config traits based on existing pallet config traits in a safe and developer-friendly way.

Type Definitions

• Account
  The full account information for a particular account ID.
• BlockHash
  Map of block numbers to block hashes.
• LastRuntimeUpgrade
  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.
• Origin
  Exposed trait-generic origin type.
