Struct ckb_verification::TransactionSnapshot

pub struct TransactionSnapshot {
    pub current: usize,
    pub snaps: Vec<(Snapshot, u64, ResumePoint), Global>,
    pub current_cycles: u64,
    pub limit_cycles: u64,
}

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, u64, ResumePoint), Global>

vm snapshots

current_cycles: u64

current consumed cycle

limit_cycles: u64

limit cycles when snapshot create

Implementations

impl TransactionSnapshot

pub fn next_limit_cycles( &self, step_cycles: u64, max_cycles: u64 ) -> (u64, bool)

Return next limit cycles according to max_cycles and step_cycles
