Enum sp_io::KillStorageResult [−][src]
Expand description
The outcome of calling storage_kill
. Returned value is the number of storage items
removed from the trie from making the storage_kill
call.
Variants
AllRemoved(u32)
No key remains in the child trie.
SomeRemaining(u32)
At least one key still resides in the child trie due to the supplied limit.

type SelfInstance = T
type SelfInstance = T
As Self
can be an unsized type, it needs to be represented by a sized type at the host.
This SelfInstance
is the sized type. Read more
