Trait Implementations

impl<U: Clone + Unit> Clone for CalcFunction<U>

fn clone(&self) -> CalcFunction<U>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<U: Debug + Unit> Debug for CalcFunction<U>

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

Formats the value using the given formatter.

impl<U: Unit> Default for CalcFunction<U>

fn default() -> Self

Returns the “default value” for a type.

impl<U: Unit> Expression<U> for CalcFunction<U>

fn evaluate<Conversion: FontRelativeLengthConversion<U::Number> + ViewportPercentageLengthConversion<U::Number> + PercentageConversion<U::Number> + AttributeConversion<U> + CssVariableConversion>( &self, conversion: &Conversion, ) -> Option<U::Number>

Evaluate the CalcFunction by returning the numeric value of the canonical dimension Division by zero is handled by returning the maximum possible f32 value Subtractions for UnsignedCssNumber that are negative are handled by returning 0.0

impl<U: Hash + Unit> Hash for CalcFunction<U>

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<U: Ord + Unit> Ord for CalcFunction<U>

fn cmp(&self, other: &CalcFunction<U>) -> 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<U: PartialEq + Unit> PartialEq for CalcFunction<U>

fn eq(&self, other: &CalcFunction<U>) -> 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<U: PartialOrd + Unit> PartialOrd for CalcFunction<U>

fn partial_cmp(&self, other: &CalcFunction<U>) -> 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<U: Unit> ToCss for CalcFunction<U>

fn to_css<W: Write>(&self, dest: &mut W) -> Result

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

impl<U: Eq + Unit> Eq for CalcFunction<U>
