An error found during schema validation against a protocol.

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.

InvalidEdge

An edge violates the protocol’s edge rules.

Fields

src: String

The offending edge’s source vertex ID.

tgt: String

The offending edge’s target vertex ID.

kind: String

The edge kind.

reason: String

Human-readable reason for the violation.

InvalidConstraintSort

A constraint uses a sort not recognized by the protocol.

Fields

vertex: String

The vertex with the invalid constraint.

sort: String

The unrecognized sort.

InvalidVertexKind

A vertex kind is not recognized by the protocol.

Fields

vertex: String

The vertex ID.

kind: String

The unrecognized kind.

DanglingRequiredEdge

A required edge references a missing vertex.

Fields

vertex: String

The vertex ID.

edge: String

The dangling edge description.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl PartialEq for ValidationError

fn eq(&self, other: &ValidationError) -> 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 ValidationError

impl StructuralPartialEq for ValidationError
