Implementations

impl RollbackAccounts

pub fn count(&self) -> usize

Number of accounts tracked for rollback

pub fn iter(&self) -> RollbackAccountsIter<'_>

Iterator over accounts tracked for rollback.

pub fn data_size(&self) -> usize

Size of accounts tracked for rollback, used when calculating the actual cost of transaction processing in the cost model.

Trait Implementations

impl Clone for RollbackAccounts

fn clone(&self) -> RollbackAccounts

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RollbackAccounts

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

Formats the value using the given formatter.

impl<'a> IntoIterator for &'a RollbackAccounts

type Item = &'a (Address, AccountSharedData)

The type of the elements being iterated over.

type IntoIter = RollbackAccountsIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for RollbackAccounts

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