Shared decoder errors, including unsupported encodings and decoded-size limits. This replaces the former XML-only error variants rather than collapsing new failure classes into misleading legacy variants. Failure while converting external bytes into the Unicode XML parser contract.

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.

UnsupportedByteEncoding(&'static str)

The byte signature selected an encoding that this implementation cannot decode.

UnsupportedEncoding(String)

An encoding label was not recognized.

ConflictingEncoding(String)

Resolver metadata, a byte signature, and the XML declaration disagreed.

MalformedDeclaration(&'static str)

The XML declaration was malformed before parsing could begin.

InvalidBytes(&'static str)

The selected decoder rejected malformed input instead of replacing it.

MissingUtf16ByteOrder

A BOM-less UTF-16 document did not identify its byte order.

MissingUtf32ByteOrder

A UTF-32 document did not identify its byte order through metadata or its signature.

MissingEncodingDeclaration(&'static str)

A non-UTF-8/UTF-16 entity omitted both external encoding metadata and its declaration.

InvalidUtf16Length(&'static str)

A UTF-16 code unit was truncated.

InvalidUtf32Length(&'static str)

A UTF-32 code unit was truncated.

DecodedLimit

Decoded UTF-8 would exceed the caller’s materialization ceiling.

Fields

maximum: usize

Configured maximum decoded size.

actual: usize

Minimum decoded size required by the input.

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 XmlDocumentError

fn from(source: Error) -> Self

Converts to this type from the input type.
