Enum lightningcss::values::calc::Calc

pub enum Calc<V> {
    Value(Box<V>),
    Number(CSSNumber),
    Sum(Box<Calc<V>>, Box<Calc<V>>),
    Product(CSSNumber, Box<Calc<V>>),
    Function(Box<MathFunction<V>>),
}

A mathematical expression used within the calc() function.

This type supports generic value types. Values such as Length, Percentage, Time, and Angle support calc() expressions.

Variants

Value(Box<V>)

Number(CSSNumber)

A literal number.

Sum(Box<Calc<V>>, Box<Calc<V>>)

A sum of two calc expressions.

Product(CSSNumber, Box<Calc<V>>)

A product of a number and another calc expression.

Function(Box<MathFunction<V>>)

A math function, such as calc(), min(), or max().
