Enum StorageKind

#[repr(C)]
pub enum StorageKind {
    PERSISTENT = 1,
    LOCAL = 2,
}

A type of supported crypto.

Variants

PERSISTENT = 1

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 = 2

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 copy 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<(), Error>

Formats the value using the given formatter.

impl Decode for StorageKind

fn decode<__CodecInputEdqy>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<StorageKind, Error>

where __CodecInputEdqy: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<StorageKind, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for StorageKind

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

where __CodecOutputEdqy: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

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 TryFrom<u8> for StorageKind

type Error = ()

The type returned in the event of a conversion error.

fn try_from(inner: u8) -> Result<StorageKind, ()>

Performs the conversion.
