Crate frame_support_procedural

Proc macro of Support code for the runtime.

Macros

• __create_tt_macro
  Internal macro used by frame_support to create tt-call-compliant macros
• __generate_dummy_part_checker
  Internal macro use by frame_support to generate dummy part checker for old pallet declaration
• construct_runtime
  Construct a runtime, with the given name and the given pallets.
• crate_to_crate_version
  Macro used internally in FRAME to generate the crate version for a pallet.
• impl_key_prefix_for_tuples
  This macro is meant to be used by frame-support only. It implements the trait HasKeyPrefix and HasReversibleKeyPrefix for tuple of Key.
• match_and_insert
  Macro that inserts some tokens after the first match of some pattern.

Attribute Macros

• benchmark
  An attribute macro used to declare a benchmark within a benchmarking module. Must be attached to a function definition containing an #[extrinsic_call] or #[block] attribute.
• benchmarks
  An attribute macro that can be attached to a (non-empty) module declaration. Doing so will designate that module as a benchmarking module.
• block
  An attribute macro used to specify that a block should be the measured portion of the enclosing benchmark function, This attribute is also used as a boundary designating where the benchmark setup code ends, and the benchmark verification code begins.
• call

  ---

• call_index
  Each dispatchable may also be annotated with the #[pallet::call_index($idx)] attribute, which explicitly defines the codec index for the dispatchable function in the Call enum.
• compact

  ---

• composite_enum

  ---

• config

  ---

• constant

  ---

• constant_name

  ---

• derive_impl
  This attribute can be used to derive a full implementation of a trait based on a local partial impl and an external impl containing defaults that can be overridden in the local impl.
• disable_frame_system_supertrait_check

  ---

• disable_try_decode_storage

  ---

• dynamic_pallet_params
  Define a module inside a dynamic_params module that contains dynamic parameters.
• dynamic_params
  Mark a module that contains dynamic parameters.
• error

  ---

• event

  ---

• extra_constants

  ---

• extrinsic_call
  An attribute macro used to specify the extrinsic call inside a benchmark function, and also used as a boundary designating where the benchmark setup code ends, and the benchmark verification code begins.
• feeless_if

  ---

• generate_deposit

  ---

• genesis_build

  ---

• genesis_config

  ---

• getter

  ---

• hooks

  ---

• import_section

  ---

• inherent

  ---

• inject_runtime_type
  The optional attribute #[inject_runtime_type] can be attached to RuntimeCall, RuntimeEvent, RuntimeOrigin or PalletInfo in an impl statement that has #[register_default_impl] attached to indicate that this item is generated by construct_runtime.
• instance_benchmarks
  An attribute macro that can be attached to a (non-empty) module declaration. Doing so will designate that module as an instance benchmarking module.
• no_default

  ---

• no_default_bounds

  ---

• origin

  ---

• pallet

  ---

• pallet_section

  ---

• register_default_impl
  Attach this attribute to an impl statement that you want to use with #[derive_impl(..)].
• require_transactional

  ---

• runtime
  Construct a runtime, with the given name and the given pallets.
• storage

  ---

• storage_alias

  ---

• storage_prefix

  ---

• storage_version

  ---

• 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.
• transactional
  Execute the annotated function in a new storage transaction.
• type_value

  ---

• unbounded

  ---

• validate_unsigned

  ---

• weight

  ---

• whitelist_storage

Derive Macros

• CloneNoBound
  Derive Clone but do not bound any generic.
• DebugNoBound
  Derive Debug but do not bound any generics.
• DefaultNoBound
  derive Default but do no bound any generic. Docs are at frame_support::DefaultNoBound.
• EqNoBound
  DeriveEq but do no bound any generic.
• OrdNoBound
  Derive Ord but do no bound any generic. Docs are at frame_support::OrdNoBound.
• PalletError
• PartialEqNoBound
  Derive PartialEq but do not bound any generic.
• PartialOrdNoBound
  Derive PartialOrd but do not bound any generic. Docs are at frame_support::PartialOrdNoBound.
• RuntimeDebugNoBound
  Derive Debug, if std is enabled it uses frame_support::DebugNoBound, if std is not enabled it just returns "<wasm:stripped>". This behaviour is useful to prevent bloating the runtime WASM blob from unneeded code.
