Toot

Written by dorotaC on 2025-01-23 at 13:15

I'm writing a hardware access library: #libobscura .

A new idea just popped into my mind: use a special structure for anything that does I/O.

struct Io;

impl Io {

fn device_exists(&self) -> io::Result;

...

}

I'm thinking if I had an Io trait, I could abstract it and use a #mock for #testing.

Is anyone else doing it? Is it a good idea?
