Can I start two async runtimes in two separate std thread?

[linrongbin16]

Hi,

I want to create two runtimes in a command line, let's say A and B.

A is for working for IO (include keyboard/mouse events through crossterm EventStream) and some background jobs.

B is for V8 javascript engine, because V8 is designed to run in a single thread, the thread models seems not compatible with rust async. But some javascript language features such as Promise and async need to use rust async jobs, so js runtime like deno usually spawn them to tokio's tasks, that's why I also want to create B to run with V8 engine.

Is that possible?

Yes, you can create as many runtimes as you want via the tokio::runtime::Builder builder.
