}

Instance is a compiled wazero instance.

func New

func New(ctx context.Context) (*Instance, error)

New creates a new wazero instance.

func (*Instance) Close

func (w *Instance) Close(ctx context.Context) error

Close closes the wazero runtime resource.

func (*Instance) Run

func (w *Instance) Run(ctx context.Context, stdin io.Reader, stdout, stderr io.Writer, fsMap map[string]fs.FS, args ...string) error

Run runs the wasm module with the context, arguments, and optional stdin, stdout, stderr, and filesystem map. Supply a context with a timeout or other cancellation mechanism to control execution time. Returns an error if instantiation fails.
