pub struct StorageVersion(_);
Expand description

The storage version of a pallet.

Each storage version of a pallet is stored in the state under a fixed key. See STORAGE_VERSION_STORAGE_KEY_POSTFIX for how this key is built.

Implementations

Creates a new instance of Self.

Returns the storage key for a storage version.

See STORAGE_VERSION_STORAGE_KEY_POSTFIX on how this key is built.

Put this storage version for the given pallet into the storage.

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

Panics

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.

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

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.
