Enum MeasureOnceError 

#[non_exhaustive]
pub enum MeasureOnceError<E> {
    Operation {
        stage: MeasureStage,
        source: Error<E>,
    },
    RecoveryFailed {
        failed_stage: MeasureStage,
        source: Error<E>,
        recovery_stage: MeasureStage,

    RestoreFailed {
        sample: MeasurementCapture,

    },
}

Complete one-shot-measurement failure.

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.

Operation

Failure before a pair was captured.

Fields

stage: MeasureStage

Failing stage.

source: Error<E>

Underlying driver failure.

RecoveryFailed

The primary operation failed and restoration also failed; hardware state is uncertain.

Fields

failed_stage: MeasureStage

Original failing stage.

source: Error<E>

Original failure.

recovery_stage: MeasureStage

Restoration stage that also failed.

recovery_source: Error<E>

Restoration failure.

RestoreFailed

A pair was captured, but restoration failed and hardware state is uncertain.

Fields

sample: MeasurementCapture

Captured sample remains useful with explicit qualification.

stage: MeasureStage

Failing restoration stage.

source: Error<E>

Underlying driver failure.

Trait Implementations

impl<E: Debug> Debug for MeasureOnceError<E>

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

Formats the value using the given formatter.

impl<E> Display for MeasureOnceError<E>

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

Formats the value using the given formatter.

impl<E: Eq> Eq for MeasureOnceError<E>

impl<E: Error + 'static> Error for MeasureOnceError<E>

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

The primary failure, in every variant.

RecoveryFailed carries two errors and a chain can only express one. Reporting the recovery failure as the cause would invert what happened: the primary failure is why the operation stopped, and the recovery failure is why the device was left uncertain. The recovery error stays available as an ordinary field, which is the honest place for a second independent failure.

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.
