Failure while constructing or reconciling typed graph contracts.

Variants

InvalidProjectInstanceId

A project instance identifier was malformed or used the zero sentinel.

Fields

reason: &'static str

Stable explanation suitable for diagnostics.

InvalidIdentityText

An identity component was blank, padded, too large, or contained control data.

Fields

reason: &'static str

Stable explanation suitable for diagnostics.

InvalidRepositoryPath(CoreError)

An existing repository path validator rejected a graph path.

InvalidStableKeyDigest

A persisted stable key digest did not match its canonical identity.

InvalidResolutionKeyDomain

A persisted canonical resolution-key domain was not supported.

InvalidResolutionKeyIdentity

A portable canonical resolution identity was malformed or oversized.

StableKeyCollision

Two distinct canonical identities claimed the same compact key.

Fields

digest: String

Compact digest that mapped to conflicting canonical material.

ProjectQualificationMismatch

A persisted entity key did not retain its project-qualified prefix.

ResolutionKeyOwnerMismatch

A canonical resolution key and its graph owner belonged to different projects.

CrossProjectRelation

A resolved relationship crossed project identity without federation.

GenerationMismatch

Related graph records did not belong to one complete publication.

Fields

context: &'static str

Record relationship whose generations disagreed.

InvalidGeneration

A derived graph record claimed the pre-publication zero generation.

InvalidResolution

A resolution retained a target or selector that did not identify one entity.

Fields

reason: &'static str

Stable explanation suitable for diagnostics.

InvalidSourceSpan

A source span used an invalid line or ordering.

Fields

reason: &'static str

Stable explanation suitable for diagnostics.

InvalidCoverage

Coverage state and counts disagreed.

Fields

reason: &'static str

Stable explanation suitable for diagnostics.

InvalidLimits

A query budget was zero or exceeded the absolute product ceiling.

Fields

reason: &'static str

Stable explanation suitable for diagnostics.

Trait Implementations

impl Debug for GraphContractError

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

Formats the value using the given formatter.

impl Display for GraphContractError

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

Formats the value using the given formatter.

impl Error for GraphContractError

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<CoreError> for GraphContractError

fn from(source: CoreError) -> Self

Converts to this type from the input type.
