Struct StorageTape 

pub struct StorageTape { /* private fields */ }

Every storage word a trace recorded, by storage context and slot.

Implementations

impl StorageTape

pub fn new(trace: &TransactionTrace, map: &StepMap) -> Self

Indexes every storage word trace recorded, in the storage context map computed for the step that recorded it.

pub fn transient(trace: &TransactionTrace, map: &StepMap) -> Self

Indexes every transient storage word trace recorded, the same way.

pub fn persistent_and_transient( trace: &TransactionTrace, map: &StepMap, ) -> (Self, Self)

Both tapes, StorageTape::new and StorageTape::transient, from one walk over the steps.

pub fn at(&self, step: usize, context: Option<usize>) -> StorageWords<'_>

The words known at step, in storage context context.

pub fn at_step<'a>(&'a self, map: &'a StepMap, step: usize) -> StorageWords<'a>

The words known at step, in the storage context that step runs in, with the address of that context so a ChainStorage can be asked about its slots.
