Attribute Macro frame_support::pallet_macros::origin
source · #[origin]
Expand description
The #[pallet::origin]
attribute allows you to define some origin for the pallet.
Item must be either a type alias, an enum, or a struct. It needs to be public.
E.g.:
ⓘ
#[pallet::origin]
pub struct Origin<T>(PhantomData<(T)>);
WARNING: modifying origin changes the outer runtime origin. This outer runtime origin
can be stored on-chain (e.g. in pallet-scheduler
), thus any change must be done with care
as it might require some migration.
NOTE: for instantiable pallets, the origin must be generic over T
and I
.
