Struct ckb_script::TransactionState

pub struct TransactionState {
    pub current: usize,
    pub vms: Vec<ResumableMachine>,
    pub current_cycles: Cycle,
    pub limit_cycles: Cycle,
    pub machine_context: Arc<Mutex<MachineContext>>,
}

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

Fields

current: usize

current suspended script index

vms: Vec<ResumableMachine>

vm states

current_cycles: Cycle

current consumed cycle

limit_cycles: Cycle

limit cycles

machine_context: Arc<Mutex<MachineContext>>

machine context for the vms included in this state

Implementations

impl TransactionState

pub fn new( vms: Vec<ResumableMachine>, machine_context: Arc<Mutex<MachineContext>>, current: usize, current_cycles: Cycle, limit_cycles: Cycle ) -> Self

Creates a new TransactionState struct

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
