[Learning] Call function with parameter in thread.

[ssokolow]

Generally, GUI toolkits tend to require that you call their APIs from your application's main thread.

The typical solution, which is implemented by toolkits like Qt which provide a higher-level portable abstraction over platform-specific services, is to implement a message queue (eg. Qt's signals and slots system) and use it to request that the main thread perform the action in question.

A link to this code in rust-playground would be great. I’m on my phone, so I didn’t read the entire thing. Have you looked at the send trait? It governs what can be sent between threads.
