Running futures and streams with blocking
The first approach is to use the block_on or block_on_stream functions of the executor module. Both functions block the current thread to wait for the result. It is a naive approach that is not very flexible, but it is great in the following circumstances:
- If you have only one task
- If none of your tasks read or write streams
- If you want to complete the task from a separate thread that can be blocked
You should remember that you must not call this function in asynchronous code, because the call will block the executor and your program will stop working.
