Enum DeclarationOrBad 

pub enum DeclarationOrBad<'a, D, M>
where
    D: DeclarationValue<'a, M>,
    M: NodeMetadata,
{
    Declaration(Declaration<'a, D, M>),
    Bad(BadDeclaration<'a>),
}

Either a valid declaration or a bad declaration consumed for error recovery.

Per the CSS spec, when parsing fails for both a declaration and a rule, we consume the remnants as a bad declaration to maintain error recovery.

Variants

Declaration(Declaration<'a, D, M>)

Bad(BadDeclaration<'a>)

Trait Implementations

impl<'a, D, M> Clone for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M> + Clone, M: NodeMetadata + Clone,

fn clone(&self) -> DeclarationOrBad<'a, D, M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, D, M> Debug for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M> + Debug, M: NodeMetadata + Debug,

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

Formats the value using the given formatter.

impl<'a, D, M> Hash for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M> + Hash, M: NodeMetadata + Hash,

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a, D, M> NodeWithMetadata<M> for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M>, M: NodeMetadata,

fn metadata(&self) -> M

Returns the complete aggregated metadata for this node (self + children). Default implementation merges children’s metadata with self_metadata().

fn self_metadata(&self) -> M

Returns the metadata contributed by this node itself, not including children. Most nodes don’t contribute metadata, so can simply return M::default(). Nodes like StyleRule or AtRules should return their own node kind flags here.

impl<'a, D, M> Ord for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M> + Ord, M: NodeMetadata + Ord,

fn cmp(&self, other: &DeclarationOrBad<'a, D, M>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a, D, M> PartialEq for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M> + PartialEq, M: NodeMetadata + PartialEq,

fn eq(&self, other: &DeclarationOrBad<'a, D, M>) -> 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.

impl<'a, D, M> PartialOrd for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M> + PartialOrd, M: NodeMetadata + PartialOrd,

fn partial_cmp(&self, other: &DeclarationOrBad<'a, D, M>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a, D, M> SemanticEq for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M>, M: NodeMetadata,

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

Returns true if self and other are semantically equal.

impl<'a, D, M> ToCursors for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M> + ToCursors, M: NodeMetadata,

fn to_cursors(&self, s: &mut impl CursorSink)

impl<'a, D, M> ToSpan for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M> + ToSpan, M: NodeMetadata,

fn to_span(&self) -> Span

impl<'a, D, M> Eq for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M> + Eq, M: NodeMetadata + Eq,

impl<'a, D, M> StructuralPartialEq for DeclarationOrBad<'a, D, M>

where D: DeclarationValue<'a, M>, M: NodeMetadata,
