}

Struct specifies which script has verified so far. State lifetime bound with vm machine.

Fields

current: (ScriptGroupType, Byte32)

current suspended script

remain: Vec<(ScriptGroupType, Byte32)>

remain script groups to verify

vm: ResumableMachine<'a>

vm state

current_cycles: Cycle

current consumed cycle

limit_cycles: Cycle

limit cycles

enable_backup_page_flags: bool

enable snapshot page dirty flags

flags_tracing: Vec<(u64, u64)>

tracing data as code page index

Implementations

impl TransactionState<'_>

pub fn next_limit_cycles(
    &self,
    step_cycles: Cycle,
    max_cycles: Cycle
) -> (Cycle, bool)

Return next limit cycles according to max_cycles and step_cycles
