Struct ObjectPositionStyleValue 

pub struct ObjectPositionStyleValue(pub Position);

Represents the style value for object-position as defined in css-images-5.

The object-position CSS property places images, videos, and other replaced elements within their boxes.

The grammar is defined as:

<position>

0: Position

Trait Implementations

impl Clone for ObjectPositionStyleValue

fn clone(&self) -> ObjectPositionStyleValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectPositionStyleValue

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

Formats the value using the given formatter.

impl DeclarationMetadata for ObjectPositionStyleValue

fn initial() -> &'static str

Returns the initial value of this property, as a string

fn applies_to() -> AppliesTo

Determines what types of frames this rule applies to

fn animation_type() -> AnimationType

Returns how this style value animates

fn percentages() -> Percentages

Determines how this style value resolves percentages, if they are allowed as values

fn property_group() -> PropertyGroup

Returns which CSS specification(s) this property belongs to. This allows tracking which CSS modules are used in a stylesheet.

fn computed_value_type() -> ComputedValueType

Returns how the computed value is calculated from the specified value.

fn canonical_order() -> Option<&'static str>

Returns the canonical order for serialization (e.g., “per grammar”, “unique”). Returns None if not specified or not applicable.

fn inherits() -> Inherits

Determines if this style value inherits from parent rules

fn is_shorthand() -> bool

Determines if this style value is a “shorthand” value, meaning it is comprised of other “longhand” style values.

fn is_longhand() -> bool

Determines if this style value is a “longhand” value, meaning a “shorthand” style value exists that could also express this.

fn longhands() -> Option<&'static [CssAtomSet]>

Returns all transitive longhands for a shorthand property. For nested shorthands (e.g., border-width), this recursively expands to include all nested longhands (e.g., border-top-width, border-left-width, etc.).

fn shorthand_group() -> CssAtomSet

Returns the declaration ID of the shorthand that this property is part of. If this is not a longhand then it will be CssAtomSet::_None.

fn logical_property_group() -> Option<CssAtomSet>

Returns the logical property group this property belongs to (e.g., “Margin”, “Border”). This groups related logical/physical properties together. Returns None if this is not part of a logical property group.

fn box_side() -> BoxSide

Returns which side(s) of the box this property applies to. For example, margin-top returns BoxSide::Top, while margin returns all sides. Returns BoxSide::none() if the property doesn’t apply to a specific side.

fn box_portion() -> BoxPortion

Returns which portion(s) of the box model this property affects. For example, margin-top returns BoxPortion::Margin, border-width returns BoxPortion::Border. Returns BoxPortion::none() if the property doesn’t affect the box model.

fn unitless_zero_resolves() -> UnitlessZeroResolves

Returns how unitless zero resolves for this property.

impl Hash for ObjectPositionStyleValue

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 ObjectPositionStyleValue

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 ObjectPositionStyleValue

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

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

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

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

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 ObjectPositionStyleValue

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

Returns true if self and other are semantically equal.

impl ToCursors for ObjectPositionStyleValue

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

impl ToSpan for ObjectPositionStyleValue

fn to_span(&self) -> Span
