Struct casper_execution_engine::shared::execution_journal::ExecutionJournal

pub struct ExecutionJournal(/* private fields */);

A log of all transforms produced during execution.

Implementations

impl ExecutionJournal

pub fn new(inner: Vec<(Key, Transform)>) -> Self

Constructs a new ExecutionJournal.

pub fn is_empty(&self) -> bool

Whether the journal is empty.

pub fn len(&self) -> usize

How many transforms are recorded in the journal.

pub fn push(&mut self, entry: (Key, Transform))

Adds a transform to the journal.

pub fn iter(&self) -> impl Iterator<Item = &(Key, Transform)>

Returns an iterator over the journal entries.

Trait Implementations

impl Clone for ExecutionJournal

fn clone(&self) -> ExecutionJournal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for ExecutionJournal

const IS_DYNAMIC: bool = true

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for ExecutionJournal

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

Formats the value using the given formatter.

impl Default for ExecutionJournal

fn default() -> ExecutionJournal

Returns the “default value” for a type.

impl Extend<(Key, Transform)> for ExecutionJournal

fn extend<I: IntoIterator<Item = (Key, Transform)>>(&mut self, iter: I)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl From<&ExecutionJournal> for ExecutionEffect

fn from(execution_journal: &ExecutionJournal) -> Self

Converts to this type from the input type.

impl From<ExecutionJournal> for AdditiveMap<Key, Transform>

fn from(journal: ExecutionJournal) -> Self

Converts to this type from the input type.

impl From<ExecutionJournal> for ExecutionEffect

fn from(execution_journal: ExecutionJournal) -> Self

Converts to this type from the input type.

impl From<ExecutionJournal> for ExecutionEffect

fn from(journal: ExecutionJournal) -> Self

Converts to this type from the input type.

impl IntoIterator for ExecutionJournal

type Item = (Key, Transform)

The type of the elements being iterated over.

type IntoIter = IntoIter<<ExecutionJournal as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for ExecutionJournal

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