Enum CalcSumOperator 

#[repr(C, u8)]
pub enum CalcSumOperator {
    Add(Plus),
    Subtract(Dash),
}

The + or - operator inside a <calc-sum>.

Per https://drafts.csswg.org/css-values-4/#calc-syntax, whitespace is required on both sides of these operators (unlike * and /), since 1px -2px (no space before -) must lex as two adjacent values rather than a subtraction. This is why Parse/Peek are hand-written here.

Variants

Add(Plus)

Subtract(Dash)

Trait Implementations

impl Clone for CalcSumOperator

fn clone(&self) -> CalcSumOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CalcSumOperator

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

Formats the value using the given formatter.

impl Hash for CalcSumOperator

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 NodeWithMetadata<CssMetadata> for CalcSumOperator

fn self_metadata(&self) -> CssMetadata

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.

fn metadata(&self) -> CssMetadata

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

impl Ord for CalcSumOperator

fn cmp(&self, other: &CalcSumOperator) -> 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> Parse<'a> for CalcSumOperator

fn parse<I>(p: &mut Parser<'a, I>) -> ParserResult<Self>

where I: Iterator<Item = Cursor> + Clone,

fn try_parse<I>(p: &mut Parser<'a, I>) -> Result<Self, Diagnostic>

where I: Iterator<Item = Cursor<Token>> + Clone,

impl PartialEq for CalcSumOperator

fn eq(&self, other: &CalcSumOperator) -> 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 PartialOrd for CalcSumOperator

fn partial_cmp(&self, other: &CalcSumOperator) -> 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> Peek<'a> for CalcSumOperator

fn peek<I>(p: &Parser<'a, I>, c: Cursor) -> bool

where I: Iterator<Item = Cursor> + Clone,

const PEEK_KINDSET: KindSet = KindSet::ANY

impl SemanticEq for CalcSumOperator

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

Returns true if self and other are semantically equal.

impl Serialize for CalcSumOperator

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToCursors for CalcSumOperator

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

impl ToSpan for CalcSumOperator

fn to_span(&self) -> Span

Returns source span.

impl TypeLayout for CalcSumOperator

const TYPE_LAYOUT: TypeLayoutInfo

impl Visitable for CalcSumOperator

fn accept<__V: Visit>(&self, v: &mut __V) -> VisitFlow

impl VisitableMut for CalcSumOperator

fn accept_mut<__V: VisitMut>(&mut self, v: &mut __V)

impl Copy for CalcSumOperator

impl Eq for CalcSumOperator
