Struct ckb_script::TransactionSnapshot

pub struct TransactionSnapshot {
    pub current: usize,
    pub snap: Option<(Snapshot, Cycle)>,
    pub current_cycles: Cycle,
    pub limit_cycles: Cycle,
}

Struct specifies which script has verified so far. Snapshot is lifetime free, but capture snapshot need heavy memory copy

Fields

current: usize

current suspended script index

snap: Option<(Snapshot, Cycle)>

vm snapshot

current_cycles: Cycle

current consumed cycle

limit_cycles: Cycle

limit cycles when snapshot create

Implementations

impl TransactionSnapshot

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
