Enum PinError 

pub enum PinError {
    WrongLease,
    WrongPinId(u8),
    LeaseMapPoisoned,
}

Enum representing possible failures when working with abstract GPIO pins.

• WrongLease - Client tries to obtain an input pin for a given pin_id when there is one or more output pins for a given pin_id.
• WrongPinId - Client tries to pass a bogus pin id which is not recognized by this crate registers mapping. This may be caused when pin ID is not taken from pin_map::PinId enum but created manually by other means.

Variants

WrongLease

WrongPinId(u8)

LeaseMapPoisoned

Trait Implementations

impl Debug for PinError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PinError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for PinError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
