Struct InstanceEntry 

pub struct InstanceEntry {
    pub instance_ref: CapHashOrRef,
    pub image_hash_chain: CapHash,
    pub image_hash: CapHash,
    pub program: Arc<PvmProgram>,
    pub root_cnode: CNodeCap,
    pub yield_marker_slot: Option<SlotIdx>,
    pub pinned_slots: Vec<SlotIdx>,
    pub regs: Regs,
    pub mem: Mem,
    pub gas: GasCounter,
    pub status: EntryStatus,
}

In-flight state of an Instance currently on the call stack.

Owns the working root cnode, regs, and memory of this invocation. The Vm updates these in place as the interpreter runs. The program is shared (Arc) — multiple in-flight entries can share the same predecoded bytecode (e.g. siblings of the same image).

Fields

instance_ref: CapHashOrRef

Reference back to the CacheDirectory entry this invocation is running. Carried across the apply so the post-HALT settle can hash the final working state into a CapHash.

image_hash_chain: CapHash

Cached for quick read of the Instance’s type identity.

image_hash: CapHash

Cached for quick read of the bound Image hash.

program: Arc<PvmProgram>

Predecoded bytecode (keyed by image_hash in ImageCache).

root_cnode: CNodeCap

MainFrame cnode — the active CapTable. Owned by this entry; on HALT it’s commit-merged back into the cache.

yield_marker_slot: Option<SlotIdx>

Image.yield_marker_slot, cached for yield routing.

pinned_slots: Vec<SlotIdx>

Sorted slot indices declared pinned by this Image. Cached for fast is_pinned checks.

regs: Regs

Working registers.

mem: Mem

Working memory (mapped RW overlays + ephemeral).

gas: GasCounter

Local gas counter — pulls from KernelAssist::gas_meter_* against the active gas slot.

status: EntryStatus

Running vs. Waiting.

Trait Implementations

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