Trait Expression

Source 
pub trait Expression<U: Unit> {
    // Required method
    fn evaluate<Conversion: FontRelativeLengthConversion<U::Number> + ViewportPercentageLengthConversion<U::Number> + PercentageConversion<U::Number> + AttributeConversion<U> + CssVariableConversion>(
        &self,
        conversion: &Conversion,
    ) -> Option<U::Number>;
}

Required Methods§

Source

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

Evaluate the Expression 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

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
