A context grammar, resource, or expansion error.

Variants

InvalidForm

The authored shape is outside the bounded context grammar.

UnsupportedKeyword(String)

A JSON-LD keyword is outside the accepted subset.

TermCollision(String)

Two imports assign different meanings to the same term.

VocabCollision

Two imports assign different default vocabularies.

ProtectedTermRedefinition(String)

A narrower scope changed a protected inherited definition.

DuplicateImport(String)

One resource appeared twice in a transitive import closure.

ImportCycle(String)

An import recurs into an active resource.

ImportDepthExceeded(usize)

The finite context import depth budget was exceeded.

PathEscape

A local reference leaves the supplied root.

ResourceUnavailable(String)

The caller did not supply this resource.

ResourceUntrusted(String)

An explicit nonlocal resource has not been trusted by the caller.

DigestMismatch(String)

The bytes do not match a content-addressed reference.

RemoteForbidden(String)

HTTP and other remote schemes are not context references.

RelativeImportWithoutBase

A digest-addressed context cannot resolve a local child.

InvalidTarget(String)

A target is not a canonical semantic node address.

UnboundKey(String)

No binding, prefix, or default vocabulary names the key.

InvalidNodeLink

A node-link value is not a canonical node URI string.

MissingJsonDatatype

The schema closure did not supply the @json datatype.

InvalidFactObject

A non-JSON fact object needs a recognized expanded value or node form.

InvalidResource(String)

A supplied context file is malformed or has the wrong envelope.

Trait Implementations

impl Clone for ContextError

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 ContextError

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

Formats the value using the given formatter.

impl Display for ContextError

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

Formats the value using the given formatter.

impl Eq for ContextError

impl Error for ContextError

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<ContextError> for DocumentGraphError

fn from(source: ContextError) -> Self

Converts to this type from the input type.

impl PartialEq for ContextError

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

Equality operator ==.

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

Inequality operator !=.
