Creating a new Handle

[duarten]

runtime::Handle::new is private, so I'm not sure how to create an instance of it?

This is what I got from browsing the docs:

Users should obtain a handle from one of the Vortex runtime’s and use it to spawn new async tasks, blocking I/O tasks, CPU-heavy tasks, or to open files for reading or writing. - https://docs.rs/vortex/latest/vortex/io/runtime/struct.Handle.html

I guess you have to make a SingleThreadRuntime, then you can get its handle:

https://docs.rs/vortex/latest/vortex/io/runtime/single/struct.SingleThreadRuntime.html#method.default

https://docs.rs/vortex/latest/vortex/io/runtime/single/struct.SingleThreadRuntime.html#method.handle

I guess you use a SingleThreadRuntime handle to make a tokio handle if that's what you want. Don't see how to make a multithreaded handle or runtime. 🤷

There’s also TokioRuntime::current which relies on the existence of an active Tokio Runtime. This is admittedly not documented well. We should add something to the runtime module docs. @duarten does any of this address your needs?

[duarten]

I think so, thank you! I think it's also interesting to note that TokioRuntime::current() doesn't need a runtime available at the time of the call, but later on when vortex actually wants to schedule work.

That is indeed interesting and should probably be in the docs!
