Trait Led 

pub trait Led {
    // Required methods
    fn init(&self);
    fn on(&self);
    fn off(&self);
    fn toggle(&self);
    fn read(&self) -> bool;
}

Simple on/off interface for LED pins.

Since GPIO pins are synchronous in Tock the LED interface is synchronous as well.

Required Methods

fn init(&self)

Initialize the LED. Must be called before the LED is used.

fn on(&self)

Turn the LED on.

fn off(&self)

Turn the LED off.

fn toggle(&self)

Toggle the LED.

fn read(&self) -> bool

Return the on/off state of the LED. true if the LED is on, false if it is off.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
