}

A metadata storage error.

Collects the backend-neutral domain errors any backend can raise, alongside the backend’s own error type MErr carried by Backend.

Stability

This enum is #[non_exhaustive].

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.

IntegerConversionError(TryFromIntError)

An integer conversion error.

InvalidRunState(String)

Encountered an invalid run state.

InvalidExplosion

Invoked an explosion on an already-resolved dimension.

Fields

task: &'static str

The name of the task on which the invalid explosion was invoked.

dim: &'static str

The dimension name this explosion tried to resolve.

MissingTicketSummary

Missing ticket summary for a task.

Fields

task: &'static str

The name of the task whose ticket summary is missing.

MissingResolution

Missing resolution for a dimension.

Fields

dim: &'static str

The name of the dimension that is missing a resolution.

deps: Vec<(&'static str, usize)>

The ancestor coordinates of this resolution.

Internal(&'static str)

Unspecified internal error.

SchemaLocked(String)

Tried to run two instances of Operon against the same metadata schema.

LockLost(String)

Lost the advisory lock on the metadata schema.

Backend(MErr)

An error from a specific metadata backend.

RebuildBackend(MemMetaError)

An error from the scratch in-memory store during the rebuild phase.

Trait Implementations

impl<MErr: Debug> Debug for MetaStorageError<MErr>

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

Formats the value using the given formatter.

impl<MErr> Display for MetaStorageError<MErr>

where MErr: Display,

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

Formats the value using the given formatter.

impl<MErr> Error for MetaStorageError<MErr>

where MErr: Error, Self: Debug + Display,

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
