Errors returned by the migration-only importer.

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.

WriteTransactionRequired

The transaction was not opened with SQLite’s writer lock.

IdentityConflict

Existing identity has different immutable event content.

Fields

existing_row_id: RowId

Existing Dovecote row that conflicted with the imported event.

ImportConflict

Existing delivery state differs from the requested imported state.

Fields

existing_row_id: RowId

Existing Dovecote row whose delivery state conflicted.

Configuration

The adapter configuration is not valid for SQLite.

Fields

detail: String

Diagnostic describing the invalid configuration.

InvalidState

Imported state failed Dovecote validation.

Fields

source: ValidationError

Original validation error.

MigrationMismatch

Installed durable schema is incompatible with this adapter.

Fields

detail: String

Diagnostic describing the incompatible schema.

Serialization

Stored or returned data could not be represented safely.

Fields

detail: String

Diagnostic describing the invalid stored data.

BusyExhausted

A caller transaction remained blocked after the configured busy wait.

Fields

operation: &'static str

Operation being performed when the lock wait was exhausted.

source: Error

Original underlying SQLite error.

Sql

A non-busy SQLx operation failed.

Fields

operation: &'static str

Operation being performed when SQL failed.

source: Error

Original underlying SQLite error.

Trait Implementations

impl Debug for ImportError

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

Formats the value using the given formatter.

impl Display for ImportError

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

Formats the value using the given formatter.

impl Error for ImportError

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.
