slot: Slot

Implementations

impl<'a> ShrinkInProgress<'a>

pub(crate) fn new_storage(&self) -> &Arc<AccountStorageEntry>

pub(crate) fn old_storage(&self) -> &Arc<AccountStorageEntry>

Trait Implementations

impl<'a> Debug for ShrinkInProgress<'a>

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

Formats the value using the given formatter.

impl<'a> Drop for ShrinkInProgress<'a>

called when the shrink is no longer in progress. This means we can release the old append vec and update the map of slot -> append vec

fn drop(&mut self)

Executes the destructor for this type.
