impl Ord for VarFunction

fn cmp(&self, __arg_0: &VarFunction) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

impl PartialOrd for VarFunction

fn partial_cmp(&self, __arg_0: &VarFunction) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &VarFunction) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &VarFunction) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &VarFunction) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &VarFunction) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Eq for VarFunction

impl PartialEq for VarFunction

fn eq(&self, __arg_0: &VarFunction) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &VarFunction) -> bool

This method tests for !=.

impl Hash for VarFunction

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl ToCss for VarFunction

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: Unit> Expression<U> for VarFunction

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

Evaluate the VarFunction 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
