A trait that defines a standard interface for a GPIO driver. This trait manages a collection of GPIO pins.

Required Methods

fn setup( &mut self, pin: u32, callback: impl FnMut(u32, EventType) + 'a, ) -> Result<(), i32>

Initializes a GPIO pin and registers a callback for events.

fn set_direction(&mut self, pin: u32, direction: Direction) -> Result<(), i32>

Sets the direction of a GPIO pin.

fn set_output_mode(&mut self, pin: u32, mode: OutputMode) -> Result<(), i32>

Sets the output mode of a GPIO pin.

fn set_pull_resistor( &mut self, pin: u32, resistor: PullResistor, ) -> Result<(), i32>

Sets the internal pull-up or pull-down resistor for a GPIO pin.

fn set_event_trigger( &mut self, pin: u32, trigger: EventTrigger, ) -> Result<(), i32>

Sets the event trigger for a GPIO pin.

fn set_output(&mut self, pin: u32, value: bool)

Sets the output level of a GPIO pin. value is true for high, false for low.

fn get_input(&self, pin: u32) -> bool

Gets the input level of a GPIO pin. Returns true for high, false for low.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
