Struct GenericAnchorFunctionFallback 

pub struct GenericAnchorFunctionFallback<L> {
    pub node: GenericCalcNode<L>,
    /* private fields */
}

Fallback type for anchor functions within calc(). Ideally, the fallback type is initial type of the property (e.g. GenericInset for left), but that causes circular reference. TODO(dshin, bug 2034100): Investigate ways to not require this. This handles the parsing of unitless zeros, as well as ensuring that e.g. calc(anchor(--foo left, 1px) + 10%) round trips (sorting aside), instead of becoming calc(anchor(--foo left, calc(1px)) + 10%).

Fields

node: GenericCalcNode<L>

The parsed fallback value. Stored as a calc node to break the circular reference.

Implementations

impl<L> GenericAnchorFunctionFallback<L>

pub fn new(is_calc_node: bool, node: GenericCalcNode<L>) -> Self

Create a new anchor function fallback value.

Trait Implementations

impl<L: Clone> Clone for GenericAnchorFunctionFallback<L>

fn clone(&self) -> GenericAnchorFunctionFallback<L>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<L: Debug> Debug for GenericAnchorFunctionFallback<L>

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

Formats the value using the given formatter.

impl<'de, L> Deserialize<'de> for GenericAnchorFunctionFallback<L>

where L: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<L> MallocSizeOf for GenericAnchorFunctionFallback<L>

where L: MallocSizeOf,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<L: PartialEq> PartialEq for GenericAnchorFunctionFallback<L>

fn eq(&self, other: &GenericAnchorFunctionFallback<L>) -> 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<L> Serialize for GenericAnchorFunctionFallback<L>

where L: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<L> ToAnimatedZero for GenericAnchorFunctionFallback<L>

where L: ToAnimatedZero,

fn to_animated_zero(&self) -> Result<Self, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation’s “by-animation” where SMIL first interpolates from the zero value to the ‘by’ value, and then adds the result to the underlying value.

impl<L: CalcNodeLeaf> ToCss for GenericAnchorFunctionFallback<L>

fn to_css<W>(&self, dest: &mut CssWriter<'_, W>) -> Result

where W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

fn to_css_cssstring(&self) -> String

Serialize self in CSS syntax and return a CssString.

impl<L> ToResolvedValue for GenericAnchorFunctionFallback<L>

where L: ToResolvedValue,

type ResolvedValue = GenericAnchorFunctionFallback<<L as ToResolvedValue>::ResolvedValue>

The resolved value type we’re going to be converted to.

fn from_resolved_value(from: Self::ResolvedValue) -> Self

Convert a resolved value to resolved value form.

fn to_resolved_value(self, context: &Context<'_>) -> Self::ResolvedValue

Convert a resolved value to a resolved value.

impl<L> ToShmem for GenericAnchorFunctionFallback<L>

where L: ToShmem,

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.

impl<L> StructuralPartialEq for GenericAnchorFunctionFallback<L>
