Enum StyleValue 

pub enum StyleValue<T> {
    Context(ContextValue<T>),
    Animated(T),
    Val(T),
    Unset,
    Base,
}

The value for a Style property in the public API.

This represents the result of reading a style property, with additional states like Base that indicate inheritance from parent styles.

Variants

Context(ContextValue<T>)

Value resolved from inherited context when the property is read.

Animated(T)

Value inserted by animation interpolation

Val(T)

Value set directly

Unset

Use the default value for the style, typically from the underlying ComputedStyle.

Base

Use whatever the base style is. For an overriding style like hover, this uses the base style. For the base style, this is equivalent to Unset.
