Struct bus_mapping::operation::StorageOp

pub struct StorageOp {
    pub address: Address,
    pub key: Word,
    pub value: Word,
    pub value_prev: Word,
    pub tx_id: usize,
    pub committed_value: Word,
}

Represents a READ/WRITE into the storage implied by a specific OpcodeId of the ExecStep.

Fields

address: Address

Account Address

key: Word

Storage Key

value: Word

Storage Value after the operation

value_prev: Word

Storage Value before the operation

tx_id: usize

Transaction ID: Transaction index in the block starting at 1.

committed_value: Word

Storage Value before the transaction

Implementations

impl StorageOp

pub const fn new( address: Address, key: Word, value: Word, value_prev: Word, tx_id: usize, committed_value: Word ) -> StorageOp

Create a new instance of a StorageOp from it’s components.

pub const fn target(&self) -> Target

Returns the Target (operation type) of this operation.

pub const fn address(&self) -> &Address

Returns the [Address] corresponding to this storage operation.

pub const fn key(&self) -> &Word

Returns the Word used as key for this operation.

pub const fn value(&self) -> &Word

Returns the Word read or written by this operation.

pub const fn value_prev(&self) -> &Word

Returns the Word at key found previous to this operation.

Trait Implementations

impl Clone for StorageOp

fn clone(&self) -> StorageOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StorageOp

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

Formats the value using the given formatter.

impl Op for StorageOp

fn into_enum(self) -> OpEnum

Turn the Generic Op into an OpEnum so that we can match it into a particular Operation Kind.

fn reverse(&self) -> Self

Return a copy of the operation reversed.

impl Ord for StorageOp

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for StorageOp

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for StorageOp

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
