Struct TransactionSnapshot

Source 
pub struct TransactionSnapshot {
    pub current: usize,
    pub state: Option<FullSuspendedState>,
    pub current_cycles: u64,
    pub limit_cycles: u64,
}
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

§state: Option<FullSuspendedState>

vm snapshots

§current_cycles: u64

current consumed cycle

§limit_cycles: u64

limit cycles when snapshot create

Source§

impl TransactionSnapshot

Source

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