3.1 - Simple threading
The simplest threading is already covered by most Rust books. Starting up a thread, passing stuff to it, letting it run and waiting for it to finish. Something like this is the basic thread example in Rust. This work’s and is easy to … -
3.2 - Sharing data between threads
Now that we can send messages to threads I want to see how we can access shared data from those threads. This isn’t the best design choice as shared data needs to be protected by locks so that it is accessed in an atomic fashion and … -
3.3 - Accessing the Id Manager from multiple threads
Since I now understand a little about how to share data between threads I can try and use my Id Manager from multiple threads. Following the same pattern as I’ve been using with the other threading code, something like this might … -
3.4 - Deadlocks
One reason that access shared data using locks is a bad idea is that, in complex code, it may be possible to deadlock. At their simplest, deadlocks are caused when one thread (thread a) obtains and holds a lock which another thread (thread …
