Module frame_support::dispatch

Dispatch system. Contains a macro for defining runtime modules and generating values representing lazy module function calls.

Structs

• DispatchInfo
  A bundle of static information collected from the #[pallet::weight] attributes.
• PerDispatchClass
  A struct holding value for each DispatchClass.
• PostDispatchInfo
  Weight information that is only available post dispatch. NOTE: This can only be used to reduce the weight or fee, not increase it.

Enums

• DispatchClass
  A generalized group of dispatch types.
• Pays
  Explicit enum to denote if a transaction pays fee or not.
• RawOrigin
  Origin for the System pallet.

Traits

• Callable
  Serializable version of pallet dispatchable.
• CheckIfFeeless
  Means to checks if the dispatchable is feeless.
• ClassifyDispatch
  Means of classifying a dispatchable function.
• GetDispatchInfo
  A Dispatchable function (aka transaction) that can carry some static information along with it, using the #[pallet::weight] attribute.
• OneOrMany
  A trait that represents one or many values of given type.
• Parameter
  A type that can be used as a parameter in a dispatchable function.
• PaysFee
  Indicates if dispatch function should pay fees or not.
• WeighData
  Means of weighing some particular kind of data (T).
• WithPostDispatchInfo
  Allows easy conversion from DispatchError to DispatchErrorWithPostInfo for dispatchables that want to return a custom a posterior weight on error.

Functions

• extract_actual_pays_fee
  Extract the actual pays_fee from a dispatch result if any or fall back to the default weight.
• extract_actual_weight
  Extract the actual weight from a dispatch result if any or fall back to the default weight.

Type Aliases

• CallableCallFor
• DispatchErrorWithPostInfo
  The error type contained in a DispatchResultWithPostInfo.
• DispatchResult
  Un-augmented version of DispatchResultWithPostInfo that can be returned from dispatchable functions and is automatically converted to the augmented type. Should be used whenever the PostDispatchInfo does not need to be overwritten. As this should be the common case it is the implicit return type when none is specified.
• DispatchResultWithPostInfo
  The return type of a Dispatchable in frame. When returned explicitly from a dispatchable function it allows overriding the default PostDispatchInfo returned from a dispatch.
