Struct VmContext

pub struct VmContext<DL>
where
    DL: CellDataProvider,
{
    pub base_cycles: Arc<AtomicU64>,
    pub message_box: Arc<Mutex<Vec<Message>>>,
    pub snapshot2_context: Arc<Mutex<Snapshot2Context<DataPieceId, SgData<DL>>>>,
}

Mutable data at virtual machine level

Fields

base_cycles: Arc<AtomicU64>

Cycles executed before current VM starts

message_box: Arc<Mutex<Vec<Message>>>

A mutable reference to scheduler’s message box

snapshot2_context: Arc<Mutex<Snapshot2Context<DataPieceId, SgData<DL>>>>

A snapshot for COW usage

Implementations

impl<DL> VmContext<DL>

where DL: CellDataProvider + Clone,

pub fn new(sg_data: &SgData<DL>, message_box: &Arc<Mutex<Vec<Message>>>) -> Self

Creates a new VM context. It is by design that parameters to this function are references. It is a reminder that the inputs are designed to be shared among different entities.

pub fn set_base_cycles(&mut self, base_cycles: u64)

Sets current base cycles

Trait Implementations

impl<DL> Clone for VmContext<DL>

where DL: CellDataProvider + Clone,

fn clone(&self) -> VmContext<DL>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
