Instance

class Instance : AutoCloseable

A live WebAssembly instance.

Instances and resources obtained from them are not safe for concurrent use. Embedders should serialize calls per instance. close is idempotent; execution access and previously obtained exported functions or memories fail fast after the instance has been closed.
