Enum sp_io::KillStorageResult

pub enum KillStorageResult {
    AllRemoved(u32),
    SomeRemaining(u32),
}

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.

Trait Implementations

impl Decode for KillStorageResult

fn decode<__CodecInputEdqy: Input>(
