Trait ToTyped

pub trait ToTyped {
    // Provided method
    fn to_typed(&self) -> Option<TypedValue> { ... }
}

Reifies a value into its Typed OM representation.

This trait is the Typed OM analogue of ToCss. Instead of serializing values into CSS syntax, it converts them into TypedValues that can be exposed to the DOM as CSSStyleValue subclasses.

This trait is derivable with #[derive(ToTyped)]. The derived implementation behaves as follows:

• For enums whose variants are all unit variants (representing keywords), it automatically reifies the value as TypedValue::Keyword, using the same serialization logic as ToCss.
• For all other cases, the derived implementation does not attempt to reify anything and falls back to the default method (which always returns None).

Over time, the derive may be extended to cover additional common patterns, similar to how ToCss supports multiple attribute annotations.

Provided Methods

fn to_typed(&self) -> Option<TypedValue>

Attempt to convert self into a TypedValue.

Returns Some(TypedValue) if the value can be reified into a property-agnostic CSSStyleValue subclass. Returns None if the value is unrepresentable, in which case reification produces a property-tied CSSStyleValue instead.
