Module pallet_asset_management::storage::child
Expand description
Operation on runtime child storages.
This module is a currently only a variant of unhashed with additional child_info.
Structs
Results concerning an operation to remove many keys.
Enums
Information related to a child state.
Type of child.
It does not strictly define different child type, it can also

The outcome of calling
storage_kill. Returned value is the number of storage items
removed from the backend from making the storage_kill call.Different possible state version.
Functions

storage_key key/valuesReturn the length in bytes of the value without reading it.
None if it does not exist.Put
value in storage under key.Put a raw byte slice into storage.

Remove
key from storage, returning its value if it had an explicit entry or None otherwise.Return the value of the item in storage under
key, or default_value if there is no
explicit entry. Ensure there is no explicit entry on return.Remove
key from storage, returning its value, or, if there was no explicit entry in storage,
