Module frame_support::pallet_macros

Contains macro stubs for all of the pallet:: macros

Attribute Macros

• call
  Allows a pallet to declare a set of functions as a dispatchable extrinsic.
• call_index
  Enforce the index of a variant in the generated enum Call.
• compact
  Declares the arguments of a call function to be encoded using [codec::Compact].
• composite_enum
  Allows defining an enum that gets composed as an aggregate enum by construct_runtime.
• config
  The mandatory attribute allowing definition of configurable types for the pallet.
• constant
  Allows adding an associated type trait bounded by Get from pallet::config into metadata.
• disable_frame_system_supertrait_check
  Allows bypassing the frame_system::Config supertrait check.
• disable_try_decode_storage
  Allows whitelisting a storage item from decoding during try-runtime checks.
• error
  Allows defining an error enum that will be returned from the dispatchable when an error occurs.
• event
  Allows defining pallet events.
• extra_constants
  Defines constants that are added to the constant field of PalletMetadata struct for this pallet.
• feeless_if
  Allows defining logic to make an extrinsic call feeless.
• generate_deposit
  Generates a helper function on Pallet that handles deposit events.
• genesis_build
  Allows you to define how the state of your pallet at genesis is built. This takes as input the GenesisConfig type (as self) and constructs the pallet’s initial state.
• genesis_config
  Allows you to define the genesis configuration for the pallet.
• getter
  Allows defining getter functions on Pallet storage.
• hooks
  The #[pallet::hooks] attribute allows you to specify a frame_support::traits::Hooks implementation for Pallet that specifies pallet-specific logic.
• import_section
  Splits a pallet declaration into multiple parts.
• inherent
  The #[pallet::inherent] attribute allows the pallet to provide inherents.
• no_default
  Ensures the trait item will not be used as a default with the #[derive_impl(..)] attribute macro.
• no_default_bounds
  Ensures the generated DefaultConfig will not have any bounds for that trait item.
• origin
  Allows a pallet to declare a type as an origin.
• pallet_section
  Declares a module as importable into a pallet via #[import_section].
• storage
  Declares a type alias as a storage item.
• storage_prefix
  Defines what storage prefix to use for a storage item when building the trie.
• storage_version
  Allows defining a storage version for the pallet.
• task_condition
  Allows defining conditions for a task to run.
• task_index
  Allows defining an index for a task.
• task_list
  Allows defining an iterator over available work items for a task.
• task_weight
  Allows defining the weight of a task.
• tasks_experimental
  Allows you to define some service work that can be recognized by a script or an off-chain worker.
• type_value
  Allows defining a struct implementing the Get trait to ease the use of storage types.
• unbounded
  Declares a storage as unbounded in potential size.
• validate_unsigned
  Allows the pallet to validate unsigned transactions.
• weight
  Allows specifying the weight of a call.
• whitelist_storage
  Declare the storage as whitelisted from benchmarking.
