Enum StorageSlotDelta 

pub enum StorageSlotDelta {
    Value(Word),
    Map(StorageMapDelta),
}

The delta of a single storage slot.

• StorageSlotDelta::Value contains the value to which a value slot is updated.
• StorageSlotDelta::Map contains the StorageMapDelta which contains the key-value pairs that were updated in a map slot.

Variants

Value(Word)

Map(StorageMapDelta)

Implementations

impl StorageSlotDelta

pub fn with_empty_value() -> StorageSlotDelta

Returns a new StorageSlotDelta::Value with an empty value.

pub fn with_empty_map() -> StorageSlotDelta

Returns a new StorageSlotDelta::Map with an empty map delta.

pub fn slot_type(&self) -> StorageSlotType

Returns the StorageSlotType of this slot delta.

pub fn is_value(&self) -> bool

Returns true if the slot delta is of type StorageSlotDelta::Value, false otherwise.

pub fn is_map(&self) -> bool

Returns true if the slot delta is of type StorageSlotDelta::Map, false otherwise.

pub fn unwrap_value(self) -> Word

Unwraps a value slot delta into a Word.

Panics

Panics if:

• self is not of type StorageSlotDelta::Value.

pub fn unwrap_map(self) -> StorageMapDelta

Unwraps a map slot delta into a StorageMapDelta.

Panics

Panics if:

• self is not of type StorageSlotDelta::Map.

Trait Implementations

impl Clone for StorageSlotDelta

fn clone(&self) -> StorageSlotDelta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageSlotDelta

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

Formats the value using the given formatter.

impl Deserializable for StorageSlotDelta

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

where R: ByteReader,

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 StorageSlotDelta

impl From<StorageSlotContent> for StorageSlotDelta

fn from(content: StorageSlotContent) -> StorageSlotDelta

Converts to this type from the input type.

impl PartialEq for StorageSlotDelta

fn eq(&self, other: &StorageSlotDelta) -> 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 Serializable for StorageSlotDelta

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

where W: ByteWriter,

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

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

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

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