Struct StorageSlot

pub struct StorageSlot {
    pub previous_or_original_value: U256,
    pub present_value: U256,
}

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

Fields

previous_or_original_value: U256

The value of the storage slot before it was changed.

When the slot is first loaded, this is the original value.

If the slot was not changed, this is equal to the present value.

present_value: U256

When loaded with sload present value is set to original value

Implementations

impl StorageSlot

pub fn new(original: U256) -> Self

Creates a new unchanged StorageSlot for the given value.

pub fn new_changed( previous_or_original_value: U256, present_value: U256, ) -> Self

Creates a new changed StorageSlot.

pub fn is_changed(&self) -> bool

Returns true if the present value differs from the original value

pub fn original_value(&self) -> U256

Returns the original value of the storage slot.

pub fn present_value(&self) -> U256

Returns the current value of the storage slot.

Trait Implementations

impl Clone for StorageSlot

fn clone(&self) -> StorageSlot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StorageSlot

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

Formats the value using the given formatter.

impl Default for StorageSlot

fn default() -> StorageSlot

Returns the “default value” for a type.

impl From<EvmStorageSlot> for StorageSlot

fn from(value: EvmStorageSlot) -> Self

Converts to this type from the input type.

impl Hash for StorageSlot

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 StorageSlot

fn eq(&self, other: &StorageSlot) -> 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.
