Error type for style resolution and inheritance processing at the schema layer.

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.

InvalidProfileOverride

A profile style attempted to override template-bearing structure.

Fields

location: String

Human-readable location hint.

InheritanceLoop

An inheritance loop was detected.

Fields

base: String

Base key that closed the cycle.

UriResolutionFailed

A file:// URI could not be resolved.

Fields

uri: String

The URI that failed to resolve.

reason: String

Reason for failure.

MissingTemplateVariantParent

A Template V3 variant references a missing parent variant.

Fields

location: String

Human-readable location hint.

selector: String

Parent selector that could not be found.

TemplateVariantCycle

A Template V3 variant parent chain contains a cycle.

Fields

location: String

Human-readable location hint.

selector: String

Selector that closed the cycle.

TemplateVariantAnchorNotFound

A Template V3 operation matched no components.

Fields

location: String

Human-readable location hint.

TemplateVariantAmbiguousAnchor

A Template V3 operation matched more than one component.

Fields

location: String

Human-readable location hint.

InvalidTemplateVariantAdd

A Template V3 add operation does not define exactly one anchor.

Fields

location: String

Human-readable location hint.

IntegrityFailure

The fetched parent style’s content did not hash to the value declared in extends-pin.

Fields

uri: String

URI of the parent that failed integrity verification.

expected: String

CID declared in the child’s extends-pin.

actual: String

CID computed from the bytes the resolver actually returned.

VersionMismatch

The fetched style declares a citum-version requirement that the running engine does not satisfy.

Fields

uri: String

URI whose citum-version requirement was unsatisfiable.

required: String

citum-version requirement declared by the style’s info block.

declared: String

Version of the running engine.

Implementations

impl ResolutionError

pub fn from_resolver_error(uri: &str, err: ResolverError) -> Self

Convert a ResolverError into a ResolutionError for a specific URI.

Trait Implementations

impl Clone for ResolutionError

fn clone(&self) -> ResolutionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolutionError

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

Formats the value using the given formatter.

impl Display for ResolutionError

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

Formats the value using the given formatter.

impl Error for ResolutionError

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 ResolutionError

fn eq(&self, other: &ResolutionError) -> 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.
