Executor-visible validation failures for logical plans.

These errors indicate that a plan cannot be safely executed against the current schema or entity definition. They are not planner bugs.

Variants

PredicateInvalid(ValidateError)

Predicate failed schema-level validation.

UnknownOrderField

ORDER BY references an unknown field.

Fields

field: String

UnorderableField

ORDER BY references a field that cannot be ordered.

Fields

field: String

IndexNotFound

Access plan references an index not declared on the entity.

Fields

index: IndexModel

IndexPrefixTooLong

Index prefix exceeds the number of indexed fields.

Fields

prefix_len: usize

field_len: usize

IndexPrefixValueMismatch

Index prefix literal does not match indexed field type.

Fields

field: String

PrimaryKeyUnsupported

Primary key field exists but is not key-compatible.

Fields

field: String

PrimaryKeyMismatch

Supplied key does not match the primary key type.

Fields

field: String

key: Key

InvalidKeyRange

Key range has invalid ordering.

Trait Implementations

impl Debug for PlanError

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

Formats the value using the given formatter.

impl Display for PlanError

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

Formats the value using the given formatter.

impl Error for PlanError

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<PlanError> for QueryError

fn from(source: PlanError) -> Self

Converts to this type from the input type.

impl From<ValidateError> for PlanError

fn from(source: ValidateError) -> Self

Converts to this type from the input type.
