A list of all possible errors.

Variants

InvalidXmlPrefixUri(TextPos)

The xmlns:xml attribute must have an http://www.w3.org/XML/1998/namespace URI.

UnexpectedXmlUri(TextPos)

Only the xmlns:xml attribute can have the http://www.w3.org/XML/1998/namespace URI.

UnexpectedXmlnsUri(TextPos)

The http://www.w3.org/2000/xmlns/ URI must not be declared.

InvalidElementNamePrefix(TextPos)

xmlns can’t be used as an element prefix.

DuplicatedNamespace(String, TextPos)

A namespace was already defined on this element.

UnexpectedCloseTag

Fields

expected: String

actual: String

pos: TextPos

Incorrect tree structure.

UnexpectedEntityCloseTag(TextPos)

Entity value starts with a close tag.

Example:

<!DOCTYPE test [ <!ENTITY p '</p>'> ]>
<root>&p;</root>

UnknownEntityReference(String, TextPos)

A reference to an entity that was not defined in the DTD.

EntityReferenceLoop(TextPos)

A possible entity reference loop.

DuplicatedAttribute(String, TextPos)

An element has a duplicated attributes.

This also includes namespaces resolving. So an element like this will lead to an error.

<e xmlns:n1='http://www.w3.org' xmlns:n2='http://www.w3.org' n1:a='b1' n2:a='b2'/>

NoRootNode

The XML document must have at least one element.

ParserError(Error)

Errors detected by the xmlparser crate.

Implementations

impl Error

pub fn pos(&self) -> TextPos

Returns the error position.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, demand: &mut Demand<'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(e: Error) -> Self

Converts to this type from the input type.
