Available on crate feature api-gpio only.

Low-level GPIO interface.

Required Methods

fn configure(gpio: Id<Self>, config: Config) -> Result<(), Error>

Configures a GPIO.

fn read(gpio: Id<Self>) -> Result<bool, Error>

Reads from a GPIO (must be configured as input).

fn write(gpio: Id<Self>, value: bool) -> Result<(), Error>

Writes to a GPIO (must be configured as output).

fn last_write(gpio: Id<Self>) -> Result<bool, Error>

Returns the last logical value written to a GPIO (must be configured as output).

fn enable(gpio: Id<Self>, falling: bool, rising: bool) -> Result<(), Error>

Enables an event to be triggered on the given conditions (at least one must be true).

fn disable(gpio: Id<Self>) -> Result<(), Error>

Disables an event from being triggered on all conditions.

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.
