Can one engine instance be used across mnany threads?

[allisterb]

I want to use the native snips_nlu_ffi library binary in a multi-threaded app. Is it safe to share one engine pointer across many threads and call functions like snips_nlu_engine_run_get_intents concurrently?

@allisterb the engine is internally protected by a mutex, so you can share it across threads and use it concurently without any problems

@fredszaq The underlying SnipsNluEngine struct is Send + Sync so I think we could get rid of this mutex (there are other mutexes at a lower level in the implementation). This would improve concurrency.

Awesome, thanks a lot.
