Enum sp_core::offchain::StorageKind
source · #[repr(C)]
pub enum StorageKind {
PERSISTENT,
LOCAL,
}
Expand description
A type of supported crypto.
Variants
PERSISTENT
Persistent storage is non-revertible and not fork-aware. It means that any value
set by the offchain worker triggered at block N(hash1)
is persisted even
if that block is reverted as non-canonical and is available for the worker
that is re-run at block N(hash2)
.
This storage can be used by offchain workers to handle forks
and coordinate offchain workers running on different forks.
LOCAL
Local storage is revertible and fork-aware. It means that any value
set by the offchain worker triggered at block N(hash1)
is reverted
if that block is reverted as non-canonical and is NOT available for the worker
that is re-run at block N(hash2)
.
