Implementations

source

impl DeltaOp

source

pub fn apply_to(&self, base: u128) -> PartialVMResult<u128>

Returns the result of delta application to base or error if postcondition is not satisfied.

source

pub fn try_into_write_op(
 self,
 state_view: &impl StateView,
 state_key: &StateKey
) -> Result<WriteOp, VMStatus>

Consumes a single delta and tries to materialize it with a given state key. If materialization succeeds, a write op is produced. Otherwise, an error VM status is returned.
