Class PanamaWasiLinker

java.lang.Object
ai.tegmentum.wasmtime4j.panama.wasi.PanamaWasiLinker
All Implemented Interfaces:
ai.tegmentum.wasmtime4j.wasi.WasiLinker, Closeable, AutoCloseable
public final class PanamaWasiLinker extends Object implements ai.tegmentum.wasmtime4j.wasi.WasiLinker
Panama implementation of a WASI-enabled linker.

This linker wraps a standard Panama linker and adds WASI functionality. Configuration methods store settings that are applied when instantiate(Store, Module) is called.

The linker accumulates configuration through method calls and creates a properly configured WASI context at instantiation time. This allows for flexible, incremental configuration of WASI settings.

Since:
1.0.0
