Async / Await

Morph supports asynchronous programming with the async and await keywords.

Async Methods​

Prefix a method declaration with async to make it asynchronous:

LoadData async method() as Tensor<float> {
    return ReadDataset();
}

An async method runs concurrently and returns a future/promise.

Awaiting Results​

Use await to wait for an async method to complete and get its result:

Init method() {
    result is await LoadData();
    Print(result);
}

Why Async?​

Async methods allow the program to perform other work while waiting for long-running operations:

  • File I/O
  • Network requests
  • Dataset loading
  • GPU computation

Example: Parallel Data Loading​

LoadTraining async method() as Tensor<float> {
    return ReadDataset("train.csv");
}

LoadValidation async method() as Tensor<float> {
    return ReadDataset("val.csv");
}

Init method() {
    trainData is await LoadTraining();
    valData is await LoadValidation();
    Print("Data loaded!");
}
