Struct frame_support::traits::StorageVersion

This function will panic iff Pallet can not be found by PalletInfo. In a runtime that is put together using construct_runtime! this should never happen.

It will also panic if this function isn’t executed in an externalities provided environment.

source

pub fn get<P: PalletInfoAccess>() -> Self

Get the storage version of the given pallet from the storage.

It will use the storage key that is associated with the given Pallet.

Panics
