Fields

image_hash_chain: CapHash

Cumulative chain hash identifying the Instance’s type.

image_hash: CapHash

Hash of the Image cap currently bound. Always content- addressed (Images are immutable).

root_cnode: CapHashOrRef

Reference to the root cnode. Hash when clean / not yet promoted for mutation; Ref while the running Instance is mutating it via CoW.

rw_overlays: Vec<RwOverlay>

Mutable byte overlays per memory mapping. Each entry’s start matches one of the Image’s MemoryMapping.start values; bytes is the per-instance content (initial state at boot, then evolves under JIT writes).

mem_size: u32

Total addressable memory size for the Instance.

regs: [u64; 13]

PVM register file (φ[0]..φ[12]).

pc: u64

Current PC. Zero between calls; updated to entry_pc at invoke start and to the post-execution PC on HALT.

gas_remaining: u64

Gas left after the last call, for callers that want to observe residual gas. Set to 0 between calls in V1.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for InstanceCap

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