Class PanamaInstancePre

java.lang.Object

ai.tegmentum.wasmtime4j.panama.PanamaInstancePre

All Implemented Interfaces:

ai.tegmentum.wasmtime4j.InstancePre, Closeable, AutoCloseable

public final class PanamaInstancePre
extends Object
implements ai.tegmentum.wasmtime4j.InstancePre

Panama FFI implementation of InstancePre.

This class wraps a native pre-instantiated module handle and provides fast instantiation capabilities. Pre-instantiation performs expensive setup work once, allowing subsequent instance creation to be significantly faster.

Since:

1.0.0
