Struct ComponentInstance

Source

pub struct ComponentInstance { /* private fields */ }

Expand description

A live WebAssembly component instance, ready for invocation.

Wraps the engine-specific instance along with Torvyn metadata (component ID, fuel state).

§Invariants

Produced by WasmEngine::instantiate.
The instance is ready for function calls.
Fuel and memory limits are applied.

§WARM PATH — created once per component, used on every invocation.
