How to handle async rwlock in bevy systems?

[lost rune]

I'm using bevy and tokio, and I have the bevy App running in a tokio task. I have a resource that I would like to share with both a bevy App and some additional code outside of bevy. The resource's struct declares some fields with Arc<RwLock<T>> types that use tokio's async RwLocks.

Is it possible to await the async RwLocks within a bevy system in order to use this resource? If not, then is the only solution to use blocking RwLocks and to run my external code on a tokio::spawn_blocking task?

Have you tried using blocking_read? https://docs.rs/tokio/latest/tokio/sync/struct.RwLock.html#method.blocking_read
