Enum DdlMigrationError 

pub enum DdlMigrationError {
    Replica(ReplicaError),
    Bookkeeping(BookkeepingError),
}

A standalone authority’s checked DDL apply can fail either in the cluster/schema machinery or in the shared write-plane policy checks. Keeping the latter typed preserves stable migration error codes all the way to the host’s HTTP renderer.

Variants

Replica(ReplicaError)

Bookkeeping(BookkeepingError)

Trait Implementations

impl Debug for DdlMigrationError

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

Formats the value using the given formatter.

impl Display for DdlMigrationError

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

Formats the value using the given formatter.

impl Error for DdlMigrationError

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<BookkeepingError> for DdlMigrationError

fn from(error: BookkeepingError) -> DdlMigrationError

Converts to this type from the input type.

impl From<DdlMigrationError> for WritePlaneError

A DDL/migration failure raised here has to surface through writeplane’s public SQL error body. The impl lives beside DdlMigrationError because it is the local type — impl From<Local> for Foreign is what the orphan rule permits.

fn from(error: DdlMigrationError) -> WritePlaneError

Converts to this type from the input type.

impl From<ReplicaError> for DdlMigrationError

fn from(error: ReplicaError) -> DdlMigrationError

Converts to this type from the input type.
