Struct bus_mapping::operation::TxLogOp

pub struct TxLogOp {
    pub tx_id: usize,
    pub log_id: usize,
    pub field: TxLogField,
    pub index: usize,
    pub value: Word,
}

Represents TxLog read/write operation.

Fields

tx_id: usize

tx_id of TxLog, starts with 1 in rw table, and it’s unique per Tx

log_id: usize

id of log entry, starts with 1 in rw table, it’s unique within Tx, currently it is also field of execution step, As field of execution step, it resets to zero (in begin_tx), and increases with each Log* step the reason why rw table’s log_id start with 1 instead of zero is that zero log_id represents no log steps(no any logs inserting) executed

field: TxLogField

field of TxLogField

index: usize

topic index if field is Topic byte index if field is Data it would be zero for other field tags

value: Word

value

Implementations

impl TxLogOp

pub fn new( tx_id: usize, log_id: usize, field: TxLogField, index: usize, value: Word ) -> TxLogOp

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

Trait Implementations

impl Clone for TxLogOp

fn clone(&self) -> TxLogOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TxLogOp

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

Formats the value using the given formatter.

impl Op for TxLogOp

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 TxLogOp

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 TxLogOp

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

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.
