there is no reactor running, must be called from the context of a Tokio 1.x runtime

Sorry, but I am confused. I am using wasm_rs_async_executor::single_threaded::block_on, and I believe it is causing this runtime error: there is no reactor running, must be called from the context of a Tokio 1.x runtime.

Is wasm_rs_async_executor designed to be used without tokio, or does it require tokio?

I happened to run into the same error for a different reason and found this issue after searching for the error message.

I was using futures_lite::future::block_on but needed to use tokio::runtime::Runtime::block_on instead.

To clarify, this error seems to be due to whatever we are trying to block on (it using tokio) as opposed to the thing we are trying to block with.
