}

Driver error with the underlying transport error preserved as E.

This type is allocation-free and remains usable in no_std builds. Match on Error::Transport or Error::Restore to inspect and recover the original bus/backend cause.

Variants

Transport(E)

A read or write failed in the configured transport.

InvalidIdentity

Probe returned identity bytes that do not identify an ADXL355.

Fields

devid_ad: u8

Analog Devices identifier byte read from DEVID_AD.

devid_mst: u8

MEMS identifier byte read from DEVID_MST.

partid: u8

Part identifier byte read from PARTID.

InvalidResponseLength

A transport returned a payload whose length violated the exact-length contract.

Fields

register: u8

First register requested by the driver.

expected: usize

Required payload length.

actual: usize

Payload length returned by the transport.

InvalidState

The device lifecycle does not permit the requested operation.

Fields

required: StateRequirement

State that must be established before retrying.

InvalidConfiguration

A register value does not represent a supported configuration.

Fields

register: u8

Register containing the unsupported value.

value: u8

Unsupported raw register value.

NotReady

Coherent data was not available within the driver’s bounded retry sequence.

Timeout

A bounded operation timed out.

Unsupported

The requested feature is not supported by this implementation.

Restore(E)

Restoring a previously active hardware state failed.

Implementations

impl<E> Error<E>

pub fn transport_cause(&self) -> Option<&E>

Return the preserved transport cause when the error came from bus access.

pub const fn is_restore_failure(&self) -> bool

Return true when the failure happened while restoring device state.

Trait Implementations

impl<E: Clone> Clone for Error<E>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for Error<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for Error<E>

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

Formats the value using the given formatter.

impl<E: Eq> Eq for Error<E>

impl<E> Error for Error<E>

where E: Error + 'static,

Available on crate feature std only.

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

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

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

impl<E: PartialEq> PartialEq for Error<E>

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

Equality operator ==.

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

Inequality operator !=.
