Attribute Macro frame_support_procedural::generate_store

#[generate_store]

To generate a Store trait associating all storages, annotate your Pallet struct with the attribute #[pallet::generate_store($vis trait Store)], e.g.:

#[pallet::pallet]
#[pallet::generate_store(pub(super) trait Store)]
pub struct Pallet<T>(_);

More precisely, the Store trait contains an associated type for each storage. It is implemented for Pallet allowing access to the storage from pallet struct.

Thus when defining a storage named Foo, it can later be accessed from Pallet using <Pallet as Store>::Foo.

NOTE: this attribute is only valid when applied directly to your Pallet struct definition.
