Enum BgPosition 

pub enum BgPosition {
    Standard(Position),
    HorizontalVerticalOffset(PositionSingleValue, PositionVerticalKeyword, LengthPercentage),
    HorizontalOffsetVertical(PositionHorizontalKeyword, LengthPercentage, PositionSingleValue),
}

https://drafts.csswg.org/css-backgrounds-4/#typedef-bg-position

<bg-position> = <position> | <position-three>
<position-three> = [
  [ left | center | right ] && [ [ top | bottom ] <length-percentage> ]
|
  [ [ left | right ] <length-percentage> ] && [ top | center | bottom ]
]

Extends <position> with 3-value forms only valid in background-position.

Variants

Standard(Position)

Standard 1, 2, or 4-value <position>.

HorizontalVerticalOffset(PositionSingleValue, PositionVerticalKeyword, LengthPercentage)

[ left | center | right ] [ top | bottom ] <length-percentage> e.g. center bottom 10px

HorizontalOffsetVertical(PositionHorizontalKeyword, LengthPercentage, PositionSingleValue)

[ left | right ] <length-percentage> [ top | center | bottom ] e.g. left 10px center

Trait Implementations

impl Clone for BgPosition

fn clone(&self) -> BgPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BgPosition

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

Formats the value using the given formatter.

impl Hash for BgPosition

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 BgPosition

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 BgPosition

fn cmp(&self, other: &BgPosition) -> 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 BgPosition

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> + Clone,

impl PartialEq for BgPosition

fn eq(&self, other: &BgPosition) -> 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 BgPosition

fn partial_cmp(&self, other: &BgPosition) -> 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 BgPosition

const PEEK_KINDSET: KindSet = PositionSingleValue::PEEK_KINDSET

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

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

impl QueryableNode for BgPosition

const NODE_ID: NodeId = crate::NodeId::BgPosition

Unique identifier for this node type.

fn node_id(&self) -> NodeId

fn get_property(&self, _kind: PropertyKind) -> Option<Cursor>

Returns a cursor for the given property kind, if the node has that property. Used by attribute selectors to extract values from nodes.

impl SemanticEq for BgPosition

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

Returns true if self and other are semantically equal.

impl Serialize for BgPosition

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 BgPosition

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

impl ToSpan for BgPosition

fn to_span(&self) -> Span

impl Visitable for BgPosition

fn accept<V: Visit>(&self, v: &mut V)
