Attribute Macro main 

#[main]

Marks an async function as the main entry point.

Usage

use embedded_executor::PollingIo;

#[embedded_executor::main(PollingIo)]
async fn main(executor: _, io: _) -> std::io::Result<()> {
    // Your async code here
    executor.spawn(async { /* ... */ });
    Ok(())
}

The IO type must implement embedded_executor::runtime::Runtime.
