Diagnostics raised while analysing or projecting API versioning annotations.

Variants

VersionOutsideEnum

@version applied to a declaration that is not an enum.

Fields

target: String

DuplicateVersionEnum

Two enums in one specification carry the @version marker.

Fields

first: String

second: String

EmptyVersionEnum

The @version enum declares no members.

Fields

ident: String

DuplicateVersionValue

Two version members resolve to the same display value.

Fields

value: String

first: String

second: String

MissingVersionEnum

A lifecycle annotation appears without a @version enum in the specification.

Fields

annotation: String

decl: String

MalformedVersionReference

A lifecycle annotation argument is not an Enum::member reference.

Fields

annotation: String

decl: String

MalformedVersionMarker

A raw version marker failed to lower into a valid typed annotation.

Fields

decl: String

MalformedVersionParameter

A version parameter violates its argument or wire-location contract.

Fields

decl: String

reason: String

DuplicateVersionParameter

A version timeline declares more than one version marker or parameter.

Fields

decl: String

UnknownVersionReference

A lifecycle annotation references a version the timeline does not declare.

Fields

annotation: String

decl: String

reference: String

declared: String

UnsupportedVersionAnnotation

A rejected versioning annotation has no supported contract semantics.

Fields

name: String

decl: String

UnsupportedVersionTarget

A lifecycle annotation applied to a declaration that cannot carry it.

Fields

annotation: String

target: String

VersionedVersionEnum

The @version enum itself carries a lifecycle annotation.

Fields

annotation: String

ident: String

DuplicateLifecycleAnnotation

The same lifecycle annotation appears twice on one declaration.

Fields

annotation: String

decl: String

EmptyAvailability

@added and @removed leave an empty availability interval.

Fields

decl: String

added: String

removed: String

ChildOutsideParent

A child’s annotated interval reaches outside its parent’s interval.

Fields

decl: String

parent: String

version: String

DanglingReference

A surviving declaration references a declaration the projection drops.

Fields

decl: String

reference: String

version: String

UnversionedSpecification

A version selection was requested for a specification without a @version enum.

Fields

selection: String

UnknownSelectedVersion

A requested version is not declared by the timeline.

Fields

selection: String

declared: String

AmbiguousSelectedVersion

A requested version matches both a member ident and another member’s value.

Fields

selection: String

first: String

second: String

UnknownVersion

The projector received a version position outside the timeline.

Fields

index: usize

ConflictingSelection

Both version selection properties were set.

Fields

first: String

second: String

EmptySelection

The requested version selection is empty.

SelectionRequiresOneVersion

api_version received *, which only api_versions accepts.

Fields

selection: String

UnknownVersionLayout

The version layout property holds an unknown value.

Fields

value: String

DuplicateWireName

Two declarations available in the same version resolve to the same effective wire name inside one container.

Fields

container: String

wire: String

first: String

second: String

version: Option<String>

Trait Implementations

impl Clone for VersioningError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersioningError

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

Formats the value using the given formatter.

impl Display for VersioningError

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

impl Error for VersioningError

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<VersioningError> for ParseError

fn from(err: VersioningError) -> Self

Converts to this type from the input type.
