Struct EvmStorageSlot 

pub struct EvmStorageSlot {
    pub original_value: StorageValue,
    pub present_value: StorageValue,
    pub transaction_id: usize,
    pub is_cold: bool,
}

This type keeps track of the current value of a storage slot.

Fields

original_value: StorageValue

Original value of the storage slot

present_value: StorageValue

Present value of the storage slot

transaction_id: usize

Transaction id, used to track when storage slot was made warm.

is_cold: bool

Represents if the storage slot is cold

Implementations

impl EvmStorageSlot

pub fn new(original: StorageValue, transaction_id: usize) -> Self

Creates a new unchanged EvmStorageSlot for the given value.

pub fn new_changed( original_value: StorageValue, present_value: StorageValue, transaction_id: usize, ) -> Self

Creates a new changed EvmStorageSlot.

pub fn is_changed(&self) -> bool

Returns true if the present value differs from the original value.

pub fn original_value(&self) -> StorageValue

Returns the original value of the storage slot.

pub fn present_value(&self) -> StorageValue

Returns the current value of the storage slot.

pub fn mark_cold(&mut self)

Marks the storage slot as cold. Does not change transaction_id.

pub fn is_cold_transaction_id(&self, transaction_id: usize) -> bool

Is storage slot cold for given transaction id.

pub fn mark_warm_with_transaction_id(&mut self, transaction_id: usize) -> bool

Marks the storage slot as warm and sets transaction_id to the given value

Returns false if old transition_id is different from given id or in case they are same return Self::is_cold value.

Trait Implementations

impl Clone for EvmStorageSlot

fn clone(&self) -> EvmStorageSlot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvmStorageSlot

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

Formats the value using the given formatter.

impl Default for EvmStorageSlot

fn default() -> EvmStorageSlot

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EvmStorageSlot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for EvmStorageSlot

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EvmStorageSlot

fn eq(&self, other: &EvmStorageSlot) -> 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 EvmStorageSlot

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
