Failures from a coordinated basic reset.

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.

Busy

Another invocation owns this projector’s leadership grant.

LeadershipLost

The leader session was lost while starting, rolling back, or releasing the reset.

A release failure can occur after the reset commit was acknowledged. Callers must not infer from this variant that the reset was rolled back or did not commit.

Fields

source: BoxedProjectionError

Underlying database error.

SourceIdentityMismatch

Existing progress belongs to a different delivery source.

Fields

projector: ProjectorName

Projector whose durable identity was incompatible.

persisted: DeliverySourceId

Source identity persisted with durable progress.

configured: DeliverySourceId

Source identity configured for this reset.

SelectionIdentityMismatch

Existing progress belongs to a different projection selection.

Fields

projector: ProjectorName

Projector whose durable identity was incompatible.

persisted: ProjectionSelectionId

Selection identity persisted with durable progress.

configured: ProjectionSelectionId

Selection identity configured for this reset.

Callback

Application reset code failed and its transaction was rolled back.

Fields

source: BoxedProjectionError

Underlying application error.

Progress

Progress validation or deletion failed before commit.

Fields

source: BoxedProjectionError

Underlying database error.

CommitIndeterminate

PostgreSQL did not acknowledge the reset commit, so durable state is indeterminate.

Fields

source: BoxedProjectionError

Underlying database error.

Trait Implementations

impl Debug for ProjectionResetError

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

Formats the value using the given formatter.

impl Display for ProjectionResetError

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

Formats the value using the given formatter.

impl Error for ProjectionResetError

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.
