Expand description
A lazy call (module function and argument values) that can be executed via its dispatch
method.
Required Associated Types§
type RuntimeOrigin
type RuntimeOrigin
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 Config
…
type Info
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.
Required Methods§
fn dispatch(
self,
origin: Self::RuntimeOrigin
) -> Result<Self::PostInfo, DispatchErrorWithPostInfo<Self::PostInfo>>
fn dispatch( self, origin: Self::RuntimeOrigin ) -> Result<Self::PostInfo, DispatchErrorWithPostInfo<Self::PostInfo>>
Actually dispatch this call and return the result of it.
