Struct MemoryStackSubstate 

pub struct MemoryStackSubstate<'config> { /* private fields */ }

Implementations

impl<'config> MemoryStackSubstate<'config>

pub const fn new(metadata: StackSubstateMetadata<'config>) -> Self

pub fn logs(&self) -> &[Log]

pub const fn logs_mut(&mut self) -> &mut Vec<Log>

pub const fn metadata(&self) -> &StackSubstateMetadata<'config>

pub const fn metadata_mut(&mut self) -> &mut StackSubstateMetadata<'config>

pub fn deconstruct<B: Backend>( self, backend: &B, ) -> (impl IntoIterator<Item = Apply<impl IntoIterator<Item = (H256, H256)>>>, impl IntoIterator<Item = Log>)

Deconstruct the memory stack substate, return state to be applied. Panic if the substate is not in the top-level substate.

Panics

Panic if parent presents

pub fn enter(&mut self, gas_limit: u64, is_static: bool)

pub fn exit_commit(&mut self) -> Result<(), ExitError>

Exit commit represent successful execution of the substate.

It includes:

• swallow commit
  • gas recording
  • warmed accesses merging
• logs merging
• for account existed from substate with reset flag, remove storages by keys
• merge substate data: accounts, storages, tstorages, deletes, creates

Errors

Return ExitError that is thrown by gasometer gas calculation errors.

Panics

Cannot commit on root substate i.e. it forces to panic.

pub fn exit_revert(&mut self) -> Result<(), ExitError>

Exit revert. Represents revert execution of the substate.

Errors

Return ExitError

Panics

Cannot discard on root substate

pub fn exit_discard(&mut self) -> Result<(), ExitError>

Exit discard. Represents discard execution of the substate.

Errors

Return ExitError. At the momoet it’s not throwing any real error.

Panics

Cannot discard on root substate
