Struct CalcPercentageLeaf 

#[repr(C)]
pub struct CalcPercentageLeaf {
    pub value: NoCalcPercentage,
    pub hint: Optional<NumericBaseType>,
}

The value of a percentage leaf node that contains an associated percent hint.

Fields

value: NoCalcPercentage

The percentage value.

hint: Optional<NumericBaseType>

The base type the percentage resolves against, or None if there is no specific percent hint (this is used by CSS Typed OM when parsing an expression without the context of a property).

Implementations

impl CalcPercentageLeaf

pub fn new(value: f32, hint: Optional<NumericBaseType>) -> Self

Builds a percentage leaf with the given percent hint.

pub fn get(&self) -> f32

Returns the percentage value as a float.

pub fn numeric_type(&self) -> NumericType

Returns the numeric type of this percentage.

pub fn combined_hint(&self, other: &Self) -> Optional<NumericBaseType>

Returns the percent hint to use when merging two percentages with an arithmetic operation. Mismatched hints should be impossible after type checking.

Trait Implementations

impl Clone for CalcPercentageLeaf

fn clone(&self) -> CalcPercentageLeaf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CalcPercentageLeaf

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CalcPercentageLeaf

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl MallocSizeOf for CalcPercentageLeaf

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 PartialEq for CalcPercentageLeaf

fn eq(&self, other: &CalcPercentageLeaf) -> 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 Serialize for CalcPercentageLeaf

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToAnimatedZero for CalcPercentageLeaf

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 ToCss for CalcPercentageLeaf

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 ToResolvedValue for CalcPercentageLeaf

where NoCalcPercentage: ToResolvedValue<ResolvedValue = NoCalcPercentage>, Optional<NumericBaseType>: ToResolvedValue<ResolvedValue = Optional<NumericBaseType>>,

type ResolvedValue = CalcPercentageLeaf

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 ToShmem for CalcPercentageLeaf

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

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

impl ToTyped for CalcPercentageLeaf

where NoCalcPercentage: ToTyped,

fn to_typed(&self, dest: &mut ThinVec<TypedValue>) -> Result<(), ()>

Attempt to convert self into one or more TypedValue items.

fn to_typed_value(&self) -> Option<TypedValue>

Attempt to convert self into a TypedValue.

fn to_numeric_value(&self) -> Option<NumericValue>

Attempt to convert self into a NumericValue.

fn to_typed_value_list(&self) -> Option<TypedValueList>

Attempt to convert self into a TypedValueList.
