Enum SyntaxError 

#[non_exhaustive]
pub enum SyntaxError {
    InvalidBangMarkup,
    UnclosedPI,
    UnclosedXmlDecl,
    UnclosedComment,
    UnclosedDoctype,
    UnclosedCData,
    UnclosedTag,
    UnclosedSingleQuotedAttributeValue,
    UnclosedDoubleQuotedAttributeValue,
}

An error returned when a parsed document does not conform to the XML grammar, for example a tag opened by < that is not closed with >.

This error does not represent invalid XML constructs — for example the tags <> and </> are well-formed from a syntactic point of view.

Marked #[non_exhaustive] so that adding a new syntax diagnostic in a future release is not a breaking change for callers who match on this type.

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.

InvalidBangMarkup

The parser started to parse <!, but the input ended before it could recognize anything.

UnclosedPI

The parser started to parse a processing instruction (<?), but the input ended before the ?> sequence was found.

UnclosedXmlDecl

The parser started to parse an XML declaration (<?xml followed by white space or ?), but the input ended before the ?> sequence was found.

UnclosedComment

The parser started to parse a comment (<!--), but the input ended before the --> sequence was found.

UnclosedDoctype

The parser started to parse a DTD (<!DOCTYPE), but the input ended before the closing > character was found.

UnclosedCData

The parser started to parse <![CDATA[, but the input ended before the ]]> sequence was found.

UnclosedTag

The parser started to parse tag content, but the input ended before the closing > character was found.

UnclosedSingleQuotedAttributeValue

The parser was inside a single-quoted attribute value, but the input ended before the closing quote was found.

UnclosedDoubleQuotedAttributeValue

The parser was inside a double-quoted attribute value, but the input ended before the closing quote was found.

Trait Implementations

impl Clone for SyntaxError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SyntaxError

impl Debug for SyntaxError

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

Formats the value using the given formatter.

impl Eq for SyntaxError

impl Error for SyntaxError

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<SyntaxError> for Error

fn from(error: SyntaxError) -> Self

Creates a new Error::Syntax from the given error.

impl PartialEq for SyntaxError

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

Equality operator ==.

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

Inequality operator !=.
