Function NewComponentDeserialize

component_feat_component_model.go:93–108

NewComponentDeserialize decodes serialized bytes previously produced by [Component.Serialize] back into a [Component]. This function does not take a component-model binary as input. It only accepts the result of a prior call to [Component.Serialize].

(engine *Engine, encoded []byte)

// This function does not take a component-model binary as input. It only
// accepts the result of a prior call to [Component.Serialize].
func NewComponentDeserialize(engine *Engine, encoded []byte) (*Component, error) {
	var encodedPtr *C.uint8_t
	if len(encoded) > 0 {
		encodedPtr = (*C.uint8_t)(unsafe.Pointer(&encoded[0]))
	}
	var ptr *C.wasmtime_component_t
	err := C.wasmtime_component_deserialize(
		engine.ptr(), encodedPtr, C.size_t(len(encoded)), &ptr,
	)
	runtime.KeepAlive(engine)
	runtime.KeepAlive(encoded)
	if err != nil {
		return nil, mkError(err)
	}
	return mkComponent(ptr, engine), nil
}

// NewComponentDeserializeFile is the same as [NewComponentDeserialize] except
// the bytes are read from a file at `path`.
