Struct MockPins 

pub struct MockPins { /* private fields */ }

Self-contained mock GPIO implementation that records operations and supplies pre-seeded reads.

Call inject_read to pre-seed reads before running code that calls GPIO_READ, and call trace afterwards to inspect the ordered record of all GPIO operations.

Implementations

impl MockPins

pub fn inject_read(&mut self, pin: Pin, high: bool)

Pre-seeds a future read(pin) call to return high.

pub fn trace(&self) -> &[i32]

Returns the ordered trace of all GPIO operations performed so far.

Trait Implementations

impl Default for MockPins

fn default() -> MockPins

Returns the “default value” for a type.

impl Pins for MockPins

fn as_any(&self) -> &dyn Any

Returns self as &dyn Any to allow downcasting to a concrete type.

fn as_any_mut(&mut self) -> &mut dyn Any

Returns self as &mut dyn Any to allow downcasting to a concrete type.

fn setup(&mut self, pin: Pin, mode: PinMode) -> Result<()>

Configures the pin as either input or output (per mode).

fn clear(&mut self, pin: Pin) -> Result<()>

Resets a given pin to its default state.

fn clear_all(&mut self) -> Result<()>

Resets all pins to their default state.

fn read(&mut self, pin: Pin) -> Result<bool>

Reads the value of the given pin, which must have been previously setup as an input pin.

fn write(&mut self, pin: Pin, v: bool) -> Result<()>

Writes v to the given pin, which must have been previously setup as an output pin.
