Errors returned by gpiocdev functions.

Variants

AbiLimitation(AbiVersion, String)

An operation cannot be performed due to a limitation in the ABI version being used.

GpioChip(PathBuf, ErrorKind)

Problem accessing GPIO chip character devices

InvalidArgument(String)

An error returned when there is a problem with an argument.

NoGpioChips()

No gpiochips are available to the user.

NonuniqueLineName(String)

Returned when the strict mode of find_named_lines finds multiple lines with the same name.

OsError(Errno)

An error returned from an underlying os call.

UapiError(UapiCall, Error)

An error returned from an underlying uAPI call.

UnexpectedResponse(String)

The response to a uAPI command contained unexpected content.

UnsupportedAbi(AbiVersion, AbiSupportKind)

The platform or library does not support the requested uAPI ABI version.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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 self, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl From<Errno> for Error

fn from(source: Errno) -> Self

Converts to this type from the input type.

impl PartialEq<Error> for Error

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
