Enum VTableErased 

pub enum VTableErased {
    Direct(&'static VTableDirect),
    Indirect(&'static VTableIndirect),
}

Type-erased VTable that can hold either Direct or Indirect style.

Variant	Use Case
Direct	Concrete types: scalars, String, derived types
Indirect	Generic containers: Vec<T>, Option<T>, Arc<T>

Variants

Direct(&'static VTableDirect)

For concrete types with compile-time known traits.

Indirect(&'static VTableIndirect)

For generic containers with runtime trait resolution.
