    UnexpectedElement,
    UnexpectedAttribute,

    TypeMismatch,
    FacetViolation,
    KeyNotUnique,
    KeyRefDangling,

    Other,
}

Categorical tag for a validation issue. Use for programmatic dispatch rather than string-matching the message.

Variants

UnexpectedElement

UnexpectedAttribute

MissingRequiredElement

MissingRequiredAttribute

TypeMismatch

Lexical value doesn’t match its declared type.

FacetViolation

Value parses but a facet (pattern, enumeration, length, range, …) rejects it.

KeyNotUnique

xs:key-declared value appears more than once in scope.

KeyRefDangling

xs:keyref references a key value that doesn’t exist.

SubstitutionMismatch

An element is in a substitution group but isn’t substitutable for the expected head (incompatible type).

NillableViolation

xsi:nil="true" on a non-nillable element, or with content.

AssertionViolation

XSD 1.1 xs:assert / xs:assertion evaluated to false against the instance. cvc-assertion.

Trait Implementations

impl Clone for ValidationKind

fn clone(&self) -> ValidationKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ValidationKind

impl Debug for ValidationKind

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

Formats the value using the given formatter.

impl Eq for ValidationKind

impl PartialEq for ValidationKind

fn eq(&self, other: &ValidationKind) -> 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.
