}
[−]

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: Printable + Clone + PartialEq<Self::PostInfo> + Eq + Copy + Encode + Decode[−]

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.

Required methods

fn dispatch(
    self,
    origin: Self::Origin
) -> Result<Self::PostInfo, DispatchErrorWithPostInfo<Self::PostInfo>>[−]

Actually dispatch this call and return the result of it.
