Enum ReferenceError

pub enum ReferenceError {
    MissingRef,
    InvalidUid,
    NotFound,
    Recursive,
    Ambiguous,
}

A failure to either parse or resolve a <Reference> XML element

Enum variants are listed in order of precedence, e.g. if the parser encounters the node <Reference uid="invalid uid" ref="invalid uid" /> (a recursive reference and an invalid uid) attempting to resolve the reference will return InvalidUid instead of Recursive

Variants

MissingRef

The ref attribute is missing, so there isn’t anything to search for

InvalidUid

The ref attribute contains an invalid uid

Valid uids satisfy the regex [_a-zA-Z][_a-zA-Z0-9]*

NotFound

No elements found with the requested uid

Recursive

Reference to a reference

Ambiguous

More than one element was found with the requested uid

Trait Implementations

impl Clone for ReferenceError

fn clone(&self) -> ReferenceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReferenceError

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

Formats the value using the given formatter.

impl Display for ReferenceError

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

Formats the value using the given formatter.

impl Error for ReferenceError

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 PartialEq for ReferenceError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
