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.

UnsupportedVersion

Pack format/version is not supported by this loader revision.

Fields

artifact: String

Logical pack/artifact name for diagnostics.

field: String

Version field key (for example format_version).

value: String

Observed unsupported value.

MissingRequiredField

Required schema field is absent from the decoded payload.

Fields

artifact: String

Logical pack/artifact name for diagnostics.

field: String

Missing field key.

EmptyIdentifier

Identifier field is present but empty or whitespace-only.

Fields

artifact: String

Logical pack/artifact name for diagnostics.

field: String

Offending identifier field key.

EmptyCollection

Collection field is empty when the schema requires entries.

Fields

artifact: String

Logical pack/artifact name for diagnostics.

field: String

Empty collection field key.

OutOfBounds

Index or coordinate is outside the declared map/scene bounds.

Fields

artifact: String

Logical pack/artifact name for diagnostics.

field: String

Out-of-bounds field key.

location: ArtifactContractLocation

Optional list/grid location within the artifact.

value: String

Observed out-of-bounds value (display form).

InvalidReference

Reference field points at a missing or foreign entity.

Fields

artifact: String

Logical pack/artifact name for diagnostics.

field: String

Reference field key.

location: ArtifactContractLocation

Optional list/grid location within the artifact.

value: String

Observed reference value.

InconsistentData

Related fields disagree (counts, dimensions, cross-links).

Fields

artifact: String

Logical pack/artifact name for diagnostics.

field: String

Primary field involved in the inconsistency.

location: ArtifactContractLocation

Optional list/grid location within the artifact.

value: String

Summary of the inconsistent value or pairing.

InvalidValue

Field is present but not a legal domain value.

Fields

artifact: String

Logical pack/artifact name for diagnostics.

field: String

Invalid field key.

location: ArtifactContractLocation

Optional list/grid location within the artifact.

value: String

Observed illegal value.

Implementations

impl ArtifactContractError

pub const fn kind(&self) -> ArtifactContractKind

Stable category for this error, independent of field names and display text.

Use for routing, metrics, and fixture assertions without matching every payload-bearing variant arm.

Trait Implementations

impl Clone for ArtifactContractError

fn clone(&self) -> ArtifactContractError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArtifactContractError

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

Formats the value using the given formatter.

impl Display for ArtifactContractError

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

Formats the value using the given formatter.

impl Eq for ArtifactContractError

impl Error for ArtifactContractError

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 PartialEq for ArtifactContractError

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

Equality operator ==.

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

Inequality operator !=.
