Attribute Macro frame_support::pallet_macros::storage_version

#[storage_version]

Allows defining a storage version for the pallet.

Because the pallet::pallet macro implements GetStorageVersion, the current storage version needs to be communicated to the macro. This can be done by using the pallet::storage_version attribute:

#[frame_support::pallet]
mod pallet {
	const STORAGE_VERSION: StorageVersion = StorageVersion::new(5);

	#[pallet::pallet]
	#[pallet::storage_version(STORAGE_VERSION)]
	pub struct Pallet<T>(_);
}

If not present, the current storage version is set to the default value.
