Module polkadot_sdk_docs::polkadot_sdk::frame_runtime::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.

A FRAME based pallet. This mod is the entry point for everything else. All #[pallet::xxx] macros must be defined in this mod. Although, frame also provides an experimental feature to break these parts into different mods. See pallet_examples for more.

Modules

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

Structs

• Pallet
  A mandatory struct in each pallet. All functions callable by external users (aka. transactions) must be attached to this type (see frame::pallet_macros::call). For convenience, internal (private) functions can also be attached to this type.

Enums

• Call
  All dispatchable call functions (aka. transactions) are attached to Pallet in a impl block.
• Event
  The events tha this pallet can emit.

Traits

• Config
  Configuration trait of this pallet.

Type Aliases

• ModuleDeprecated
  Type alias to Pallet, to be used by construct_runtime.
• Value
  A storage item that this pallet contains. This will be part of the state root trie/root of the blockchain.
