Trait sp_runtime::traits::Dispatchable[−][src]

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[src]

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[src]

…

type Info[src]

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[src]

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.
