Trait sp_runtime::traits::Dispatchable

pub trait Dispatchable {
    type Origin;
    type Trait;
    type Info;
    type PostInfo: Eq + PartialEq + Clone + Copy + Encode + Decode + Printable;
    fn dispatch(
        self, 
        origin: Self::Origin
    ) -> DispatchResultWithInfo<Self::PostInfo>;
}

A lazy call (module function and argument values) that can be executed via its dispatch method.

Associated Types

type Origin

Every function call from your runtime has an origin, which specifies where the extrinsic was generated from. In the case of a signed extrinsic (transaction), the origin contains an identifier for the caller. The origin can be empty in the case of an inherent extrinsic.

type Trait

...

type Info

An opaque set of information attached to the transaction. This could be constructed anywhere down the line in a runtime. The current Substrate runtime uses a struct with the same name to represent the dispatch class and weight.

type PostInfo: Eq + PartialEq + Clone + Copy + Encode + Decode + Printable

Additional information that is returned by dispatch. Can be used to supply the caller with information about a Dispatchable that is ownly known post dispatch.
