A matrix, sensitivity, or dataset 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.

Transmission(Error)

A failure from the balanced model, its readers, or its writers.

Io(Error)

An underlying I/O failure this crate raised itself.

One the transmission model raised arrives as Error::Transmission wrapping powerio_tx::Error::Io, so a caller telling I/O apart from the rest reads Error::category rather than matching this variant.

Commit(Error)

A refused or failed destination commit (an output collision, an invalid inventory, a staging failure), carrying the registered core failure. Code and category delegate to it.

Implementations

impl Error

pub fn code(&self) -> &'static DiagnosticInfo

The registry entry for this error. The match is exhaustive over the variant set, so a new variant must be coded here before it compiles.

A hub failure keeps the hub’s own code: restating it here would give one failure two identities.

pub fn category(&self) -> ErrorCategory

Classify this error, using the hub’s taxonomy.

The match is exhaustive over the variant set, so a new variant must be classified here before it compiles.

Trait Implementations

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)>

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
