Trait sp_runtime::traits::Dispatchable

pub trait Dispatchable {
    type RuntimeOrigin: Debug;
    type Config;
    type Info;
    type PostInfo: Eq + PartialEq + Clone + Copy + Encode + Decode + Printable;

    // Required method
    fn dispatch(
        self,
        origin: Self::RuntimeOrigin
    ) -> DispatchResultWithInfo<Self::PostInfo>;
}

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

Required Associated Types

type RuntimeOrigin: Debug

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 Config

…

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 only known post dispatch.

Required Methods

fn dispatch( self, origin: Self::RuntimeOrigin ) -> DispatchResultWithInfo<Self::PostInfo>

Actually dispatch this call and return the result of it.
