Enum GpioError

#[non_exhaustive]
pub enum GpioError {
    WrongMode,
    Impl(ImplError),
}

This crate contains a variety of universal error types which can be used to universally model conditions which can typically arise for certain peripherals.

When used by HAL implementations, they allow drivers and applications alike to generically handle those situations without the error handling being specific to the hardware it is supposed to run on (which is usually not possible to implement in drivers).

All of the enums in this crate are marked as #[non_exhaustive] to allow for additions of new error kinds without requiring a breaking change and version bump. A GPIO (General input/output) specific error.

This error type contains errors specific to GPIO peripherals. Also it has an Impl kind to pass through implementation specific errors occuring while trying to use a GPIO peripheral.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

WrongMode

The peripheral is in the wrong operational mode for the intended operation

Impl(ImplError)

Implementation specific error (shared across all peripheral specific error kinds)
