Struct Options

pub struct Options<Direction = (), Lines = (), Consumer = ()> { /* private fields */ }

GPIO line values request options

Input config:

let input = Options::input(&[23, 17, 3])
    .active(Active::Low)
    .bias(Bias::PullUp)
    .consumer("my inputs");

Output config:

let output = Options::output(&[11, 20])
    .active(Active::Low)
    .drive(Drive::PushPull)
    .values([false, true])
    .consumer("my outputs");

Input with edge detection:

let input = Options::input(&[21, 13])
    .active(Active::Low)
    .bias(Bias::PullUp)
    .edge(EdgeDetect::Both)
    .consumer("my inputs");
