Implementations

impl<'a> RollbackWrapper<'a>

pub fn new(store: &'a mut dyn ClarityBackingStore) -> RollbackWrapper<'_>

pub fn from_persisted_log(
    store: &'a mut dyn ClarityBackingStore,
    log: RollbackWrapperPersistedLog
) -> RollbackWrapper<'_>

pub fn nest(&mut self)

pub fn rollback(&mut self)

pub fn depth(&self) -> usize

pub fn commit(&mut self)

impl<'a> RollbackWrapper<'a>

pub fn put(&mut self, key: &str, value: &str)

pub fn set_block_hash(
    &mut self,
    bhh: StacksBlockId,
    query_pending_data: bool
) -> Result<StacksBlockId>

query_pending_data indicates whether the rollback wrapper should query the rollback wrapper’s pending data on reads. This is set to false during (at-block …) closures, and true otherwise.
