Function NewModuleDeserialize

module.go:120–140

NewModuleDeserialize decodes and deserializes in-memory bytes previously produced by `module.Serialize()`. This function does not take a WebAssembly binary as input. It takes as input the results of a previous call to `Serialize()`, and only takes that as input. If deserialization is successful th

(engine *Engine, encoded []byte)

// produced with an `Engine` that has the same compilation options as the
// provided engine, and from the same version of this library.
func NewModuleDeserialize(engine *Engine, encoded []byte) (*Module, error) {
	var encodedPtr *C.uint8_t
	var ptr *C.wasmtime_module_t
	if len(encoded) > 0 {
		encodedPtr = (*C.uint8_t)(unsafe.Pointer(&encoded[0]))
	}
	err := C.wasmtime_module_deserialize(

		C.size_t(len(encoded)),

	runtime.KeepAlive(engine)
	runtime.KeepAlive(encoded)

// NewModuleDeserializeFile is the same as `NewModuleDeserialize` except that
// the bytes are read from a file instead of provided as an argument.
