Enum StorageValuePatch 

pub enum StorageValuePatch {
    Create {
        value: Word,
    },
    Update {
        value: Word,
    },
    Remove,
}

The patch of a single value storage slot.

Variants

Create

Records the creation of the slot with the given value.

Fields

value: Word

Update

Records that an existing slot was set to the given value.

Fields

value: Word

Remove

Records that the slot was removed.

Implementations

impl StorageValuePatch

pub fn value(&self) -> Option<Word>

Returns the new value of the slot for StorageValuePatch::Create and StorageValuePatch::Update, or None for StorageValuePatch::Remove.

pub fn patch_op(&self) -> StoragePatchOperation

Returns the StoragePatchOperation that this patch represents.

Trait Implementations

impl Clone for StorageValuePatch

fn clone(&self) -> StorageValuePatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageValuePatch

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

Formats the value using the given formatter.

impl Deserializable for StorageValuePatch

fn read_from<R: ByteReader>( source: &mut R, ) -> Result<Self, DeserializationError>

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn min_serialized_size() -> usize

Returns the minimum serialized size for one instance of this type.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

fn read_from_bytes_with_budget( bytes: &[u8], budget: usize, ) -> Result<Self, DeserializationError>

Deserializes Self from bytes with a byte budget limit.

impl Eq for StorageValuePatch

impl PartialEq for StorageValuePatch

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

Equality operator ==.

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

Inequality operator !=.

impl Serializable for StorageValuePatch

fn write_into<W: ByteWriter>(&self, target: &mut W)

Serializes self into bytes and writes these bytes into the target.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.

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

Serializes self into a vector of bytes.
