Module migration 

Some utilities for helping access storage with arbitrary key types.

Functions

clear_storage_prefix

Attempt to remove all values under a storage prefix by the module, the map’s item name and the key hash.

get_storage_value

Get a particular value in storage by the module, the map’s item name and the key hash.

have_storage_value

Get a particular value in storage by the module, the map’s item name and the key hash.

move_pallet

Move all storages from a pallet prefix to another pallet prefix.

move_prefix

Move all (key, value) after some prefix to the another prefix

move_storage_from_pallet

Move a storage from a pallet prefix to another pallet prefix.

put_storage_value

Put a particular value into storage by the module, the map’s item name and the key hash.

remove_storage_prefixDeprecated

Remove all items under a storage prefix by the module, the map’s item name and the key hash.

storage_iter

Construct iterator to iterate over map items in module for the map called item.

storage_iter_with_suffix

Construct iterator to iterate over map items in module for the map called item.

storage_key_iter

Construct iterator to iterate over map items in module for the map called item.

storage_key_iter_with_suffix

take_storage_item

Take a particular item in storage by the module, the map’s item name and the key hash.

take_storage_value
