source · 
pub struct TransactionSnapshot {
    pub current: usize,
    pub snaps: Vec<(Snapshot, Cycle, ResumePoint)>,
    pub current_cycles: Cycle,
    pub limit_cycles: Cycle,
}
Expand description

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

§snaps: Vec<(Snapshot, Cycle, ResumePoint)>

vm snapshots

§current_cycles: Cycle

current consumed cycle

§limit_cycles: Cycle

limit cycles when snapshot create
