Error raised while expanding a document.

Variants

ContextSyntax(InvalidContext)

The value of an @context entry is not a valid JSON-LD context.

ContextProcessing(Error<E>)

Processing a local, scoped or remote @context failed. This includes the failures of the document loader fetching a remote context.

InvalidIndexValue

An @index entry has a value that is not a string.

InvalidSetOrListObject

A @set or @list object has an entry other than @set/@list and @index.

InvalidReversePropertyMap

A key of a @reverse map expands to a keyword, or a keyword entry was found while @reverse is the active property.

InvalidTypeValue

An @type entry is not a string or an array of strings, or one of its values does not expand to an IRI or blank node identifier.

KeyExpansionFailed(String)

The given key could not be expanded into an IRI, and the Policy in use rejects such keys instead of dropping them.

InvalidReversePropertyValue

A reverse property has a value that is not a node object, which cannot be the subject of the reversed relation.

InvalidLanguageMapValue

A language map (@container: @language) has a value that is neither a string, null, nor an array of those.

CollidingKeywords

Two distinct keys of the same node object expand to the same keyword.

In JSON-LD 1.1 this is tolerated for @included and @type, whose values are merged instead.

InvalidIdValue

An @id entry has a value that is not a string.

InvalidIncludedValue

An @included entry contains something else than node objects.

InvalidReverseValue

A @reverse entry has a value that is not a map.

InvalidNestValue

An @nest entry has a value that is not a map (or an array of maps), or one of those maps has an entry expanding to @value.

DuplicateKey(Key)

The given key appears twice in the same JSON object.

Literal(LiteralExpansionError)

Expanding a scalar into a literal failed. See LiteralExpansionError.

Value(InvalidValue)

A value object (a map with an @value entry) is invalid. See InvalidValue.

ForbiddenVocab

A key could only be expanded through the vocabulary mapping (@vocab), which the Policy in use forbids.

ListOfLists

A list object was found among the items of another list object.

JSON-LD 1.0 only: 1.1 allows lists of lists.

Implementations

impl<E> Error<E>

pub fn code(&self) -> ErrorCode

Returns the JSON-LD error code this error is reported under, as named by the JSON-LD API specification.

impl<E> Error<E>

pub fn duplicate_key_ref(jstrict::object::Duplicate: Duplicate<&Entry>) -> Self

Builds an Error::DuplicateKey from the pair of colliding entries jstrict reports, keeping the key of the first one.

Trait Implementations

impl<E: Debug> Debug for Error<E>

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

Formats the value using the given formatter.

impl<E> Display for Error<E>

where Error<E>: Display,

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

Formats the value using the given formatter.

impl<E> Error for Error<E>

where Self: Debug + Display,

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
