Enum Error 

#[non_exhaustive]
pub enum Error<S, P> {
    Spi(S),
    Pin(P),
}

Driver error. S is the SPI error type, P is the error type of the DC and RST pins.

The state of the DC line after an error is not guaranteed, every command sets it again.

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.

Spi(S)

SPI transaction failed

Pin(P)

DC or RST pin could not be driven

Trait Implementations

impl<S: Clone, P: Clone> Clone for Error<S, P>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S: Debug, P: Debug> Debug for Error<S, P>

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

Formats the value using the given formatter.

impl<S: Debug, P: Debug> Display for Error<S, P>

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

Formats the value using the given formatter.

impl<S: Eq, P: Eq> Eq for Error<S, P>

impl<S: Debug, P: Debug> Error for Error<S, P>

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.

impl<S: Debug, P: Debug> Format for Error<S, P>

Available on crate feature defmt only.

Implemented by hand instead of derived: a derive would require S and P to be defmt::Format, which HAL error types usually are not. Debug is always there, because embedded_hal::spi::Error and digital::Error require it.

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl<S: PartialEq, P: PartialEq> PartialEq for Error<S, P>

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
