Variants

DuplicateNamespace

The schema has two definitions with the same object type.

Fields

namespace: String

Duplicate namespace name.

DuplicateRelation

A namespace has two relations or permissions with the same name.

Fields

namespace: String

Namespace containing the duplicate.

relation: String

Duplicate relation name.

NamespaceNotFound

A namespace was requested but is not present in the schema.

Fields

namespace: String

Missing namespace name.

RelationNotFound

A relation was requested but is not present in the namespace.

Fields

namespace: String

Namespace searched.

relation: String

Missing relation name.

MissingRelationReference

A schema expression references a relation that does not exist.

Fields

namespace: String

Namespace containing the owner relation.

owner: String

Relation that owns the invalid expression.

relation: &'static str

Invalid expression edge.

missing: String

Missing relation name.

MissingTupleToUsersetTarget

A tuple-to-userset target relation cannot be resolved from the known schema.

Fields

namespace: String

Namespace containing the owner relation.

owner: String

Relation that owns the invalid expression.

missing: String

Missing target relation name.

EmptyExpression

A set operation does not contain enough operands.

Fields

namespace: String

Namespace containing the owner relation.

owner: String

Relation that owns the invalid expression.

operator: &'static str

Operator name.

min_operands: usize

Minimum operand count.

Trait Implementations

impl Clone for SchemaError

fn clone(&self) -> SchemaError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SchemaError

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

Formats the value using the given formatter.

impl Display for SchemaError

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

Formats the value using the given formatter.

impl Error for SchemaError

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<SchemaError> for EngineError

fn from(error: SchemaError) -> Self

Converts to this type from the input type.

impl From<SchemaError> for ZanzibarError

fn from(source: SchemaError) -> Self

Converts to this type from the input type.

impl PartialEq for SchemaError

fn eq(&self, other: &SchemaError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for SchemaError

impl StructuralPartialEq for SchemaError
