Failures specific to reading or writing ifcXML.

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.

Malformed(String)

The document is not well-formed XML.

BadId(String)

An id attribute was not in the expected i<number> form.

InvalidScalar

A typed scalar did not contain a value of its declared kind.

Fields

kind: String

Declared scalar kind.

value: String

Invalid lexical value.

UnknownKind(String)

A non-empty explicit kind is not part of this lossless dialect.

DuplicateSlot

Two attributes or child elements of one entity name the same slot.

Fields

name: String

The second name resolving to the slot.

slot: usize

The zero-based positional slot.

MissingSlot

A positional name skips slots that no schema declares as omittable.

Fields

name: String

The name that skipped ahead.

slot: usize

The zero-based slot it names.

missing: usize

The first slot left without a value.

Namespace

An element resolved outside the selected release namespace.

Fields

element: String

Element local name.

expected: &'static str

Required namespace URI.

found: Option<String>

Resolved namespace URI, if any.

Profile

Root schema metadata disagrees with the selected release profile.

Fields

expected: &'static str

Required schema token.

found: Option<String>

Declared root schema token, if any.

Root

A strict document did not have the required root element.

Fields

found: Option<String>

First element local name, if any.

At

A parsing error with its entity/value location retained.

Fields

path: XmlPath

XPath-like parser location.

source: Box<XmlError>

Underlying typed parse error.

Write(String)

Writing to the output buffer failed.

Implementations

impl XmlError

pub fn path(&self) -> Option<&XmlPath>

Location retained by the reader, when the failure occurred in document content.

pub fn root_cause(&self) -> &Self

Innermost codec error, without discarding the inspectable path.

Trait Implementations

impl Debug for XmlError

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

Formats the value using the given formatter.

impl Display for XmlError

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

Formats the value using the given formatter.

impl Error for XmlError

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 XmlError

fn from(error: Error) -> Self

Converts to this type from the input type.
