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.

IdentityConflict

The immutable event identity conflicts with an existing row.

Fields

existing_row_id: RowId

The existing event row whose identity conflicted.

ImportConflict

The imported delivery state conflicts with an existing row.

Fields

existing_row_id: RowId

The existing event row whose delivery state conflicted.

InvalidState

The supplied legacy delivery state is invalid.

Fields

source: ValidationError

The validation failure from the domain state.

MigrationMismatch

The installed schema does not satisfy this adapter’s migration contract.

Fields

detail: String

Details identifying the incompatible schema contract.

Serialization

A database value could not be reconstructed as a valid domain value.

Fields

detail: String

Details describing the invalid stored value.

Sql

A non-transient SQL operation failed.

Fields

operation: &'static str

The adapter operation that failed.

source: Error

The underlying SQLx error.

Transient

A SQL operation failed with a retryable PostgreSQL condition.

Fields

operation: &'static str

The adapter operation that failed.

kind: TransientKind

The retryable PostgreSQL failure category.

source: Error

The underlying SQLx 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.
