Trait VariantParam 

pub trait VariantParam: 'static {
    const CATEGORY: &'static str;
    const VALUE: &'static str;
    const PARENT_VALUE: Option<&'static str>;
}

A type that participates in the variant system.

Declares its category (e.g., "graph"), value (e.g., "SimpleGraph"), and optional parent in the subtype hierarchy.

Required Associated Constants

const CATEGORY: &'static str

Category name (e.g., "graph", "weight", "k").

const VALUE: &'static str

Type name within the category (e.g., "SimpleGraph", "i32").

const PARENT_VALUE: Option<&'static str>

Parent type name in the subtype hierarchy, or None for root types.

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.
