The WASI class provides the WASI system call API and additional convenience methods for working with WASI-based applications. Each WASI instance represents a distinct environment.

v13.3.0, v12.16.0

Constructors

WASI

constructor(options: WASIOptions = definedExternally)

Properties

wasiImport

val wasiImport: {node/Dict<kotlin/Any?>=} ERROR CLASS: Symbol not found for Record<kotlin/String, kotlin/Any?>

wasiImport is an object that implements the WASI system call API. This object should be passed as the wasi_snapshot_preview1 import during the instantiation of a WebAssembly.Instance.

Functions

finalizeBindings

fun finalizeBindings(instance: Any, options: FinalizeBindingsOptions = definedExternally)

Set up WASI host bindings to instance without calling initialize() or start(). This method is useful when the WASI module is instantiated in child threads for sharing the memory across threads.

getImportObject

fun getImportObject(): Any

Return an import object that can be passed to WebAssembly.instantiate() if no other WASM imports are needed beyond those provided by WASI.

initialize

fun initialize(instance: Any)

Attempt to initialize instance as a WASI reactor by invoking its _initialize() export, if it is present. If instance contains a _start() export, then an exception is thrown.

start

fun start(instance: Any): Double

Attempt to begin execution of instance as a WASI command by invoking its _start() export. If instance does not contain a _start() export, or if instance contains an _initialize() export, then an exception is thrown.
