Crate lookit

The “Lookit!” crate checks for new devices in a cross-platform asynchronous manner. Returns the RawFd equivalent for the target platform.

• Linux: inotify on /dev/*
• Web: JavaScript event listeners
• Others: TODO

Getting Started

async fn run() {
    let mut lookit = Lookit::with_input().expect("no /dev/ access?");

    loop {
        dbg!((&mut lookit).await);
    }
}

pasts::block_on(run());

Implementation

Input

• inotify => /dev/input/event*
• window.addEventListener(“gamepadconnected”, function(e) { });

Audio

• inotify => /dev/snd/pcm*
• navigator.mediaDevices.getUserMedia(constraints).then(function(s) { }).catch(function(denied_err) {}) // only one speakers connection ever

MIDI

• inotify => /dev/snd/midi*, if no /dev/snd then /dev/midi*
• https://developer.mozilla.org/en-US/docs/Web/API/MIDIAccess

Camera

• inotify => /dev/video*
• navigator.mediaDevices.getUserMedia(constraints).then(function(s) { }).catch(function(denied_err) {})

Structs
