Enum StorageKind

#[repr(C)]
pub enum StorageKind {
    PERSISTENT = 0,
    LOCAL = 1,
}

A type of supported crypto.

Variants

PERSISTENT = 0

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 = 1

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).

Trait Implementations

impl Clone for StorageKind

fn clone(&self) -> StorageKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StorageKind

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StorageKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<StorageKind> for u32

fn from(c: StorageKind) -> Self

Converts to this type from the input type.

impl PartialEq for StorageKind

fn eq(&self, other: &StorageKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for StorageKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<u32> for StorageKind

type Error = ()

The type returned in the event of a conversion error.

fn try_from(kind: u32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for StorageKind

impl Eq for StorageKind

impl StructuralPartialEq for StorageKind
