error raised by the Interpreter.

Variants

TypeAlreadyDefined(Ident)

Type has already been defined.

Is raised if a new type with an already existing identifier is added to the MetaTypes structure.

ExpectedDynamicElement(Ident)

Expected dynamic element.

Expected the specified element to be dynamic because it is referenced as substitution group.

UnknownType(Ident)

Unknown type.

Is raised if a type identifier could not been resolved to the actual type information.

UnknownElement(Ident)

Unknown element.

Is raised if an element referenced inside the XML schema could not be resolved.

UnknownAttribute(String)

Unknown attribute.

Is raised if an attribute referenced inside the XML schema could not be resolved.

UnknownNamespace(Namespace)

Unknown namespace.

Is raised if the namespace URI could not be resolved.

UnknownNamespacePrefix(NamespacePrefix)

Unknown namespace prefix.

Is raised if the namespace prefix could not be resolved.

InvalidValue(&'static str)

Invalid value.

Is raised if a value from the XML schema is malformed or invalid.

InvalidLocalName(RawByteStr)

Invalid local name.

Is raised if conversion from a raw local name to a string has failed.

GroupMissingRef

Group is missing the ref attribute

Is raised if a group reference in the XML schema is missing the ref attribute.

AttributeGroupMissingRef

Attribute group is missing the ref attribute

Is raised if a attribute group reference in the XML schema is missing the ref attribute.

InvalidAttributeReference(Box<AttributeType>)

Invalid attribute reference.

The attribute specified in the schema is missing some information.

NoType

Unable to create type information.

Is raised if the interpreter was not able to generate a Type from the provided schema information.

ExpectedGroupType

The interpreter expected a group type (like xs:all, xs:choice or xs:sequence).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: InterpreterError) -> Self

Converts to this type from the input type.
