Struct FullSuspendedState

pub struct FullSuspendedState {
    pub total_cycles: Cycle,
    pub iteration_cycles: Cycle,
    pub next_vm_id: VmId,
    pub next_fd_slot: u64,
    pub vms: Vec<(VmId, VmState, Snapshot2<DataPieceId>)>,
    pub fds: Vec<(Fd, VmId)>,
    pub inherited_fd: Vec<(VmId, Vec<Fd>)>,
    pub terminated_vms: Vec<(VmId, i8)>,
    pub instantiated_ids: Vec<VmId>,
}

Full state representing all VM instances from verifying a CKB script. It should be serializable to binary formats, while also be able to fully recover the running environment with the full transaction environment.

Fields

total_cycles: Cycle

Total executed cycles

iteration_cycles: Cycle

Iteration cycles. Due to an implementation bug in Meepo hardfork, this value will not always be zero at visible execution boundaries. We will have to preserve this value.

next_vm_id: VmId

Next available VM ID

next_fd_slot: u64

Next available file descriptor

vms: Vec<(VmId, VmState, Snapshot2<DataPieceId>)>

Suspended VMs

fds: Vec<(Fd, VmId)>

Opened file descriptors with owners

inherited_fd: Vec<(VmId, Vec<Fd>)>

Inherited file descriptors for each spawned process

terminated_vms: Vec<(VmId, i8)>

Terminated VMs with exit codes

instantiated_ids: Vec<VmId>

Currently instantiated VMs. Upon resumption, those VMs will be instantiated.

Implementations

impl FullSuspendedState

pub fn size(&self) -> u64

Calculates the size of current suspended state, should be used to derive cycles charged for suspending / resuming.

Trait Implementations

impl Clone for FullSuspendedState

fn clone(&self) -> FullSuspendedState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FullSuspendedState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
