vm: Option<ResumableMachine<'a>>

vm state

current_cycles: Cycle

current consumed cycle

limit_cycles: Cycle

limit cycles

enable_backup_page_flags: bool

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)
