Module frame_system::pallet
source · 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 theCall
enum.
- The subset of the functions that are dispatchable can be identified either in the
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
andError
, which are listed among the Enums.
Modules
- Default implementations of
DefaultConfig
, which can be used to implementConfig
. - 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
- Configuration trait of this pallet.
- 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
- The full account information for a particular account ID.
- Map of block numbers to block hashes.
- Stores the
spec_version
andspec_name
of when the last runtime upgrade happened. - ModuleDeprecatedType alias to
Pallet
, to be used byconstruct_runtime
. - Exposed trait-generic origin type.
