Type Definition sp_runtime::
type DispatchOutcome = Result<(), DispatchError>;
This type specifies the outcome of dispatching a call to a module.
In case of failure an error specific to the module is returned.
Failure of the module call dispatching doesn’t invalidate the extrinsic and it is still included in the block, therefore all state changes performed by the dispatched call are still persisted.
For example, if the dispatching of an extrinsic involves inclusion fee payment then these changes are going to be preserved even if the call dispatched failed.
