Trait Contextuable 

pub trait Contextuable<D, S, T, ST, SYM, VS, VT>: Identifiable
where
    D: Datable + Clone,
    S: Spatial<VS> + Clone,
    T: Temporal<VT> + Clone,
    ST: SpaceTemporal<VS, VT> + Clone,
    SYM: Symbolic + Clone,

{
    // Required method
    fn vertex_type(&self) -> &ContextoidType<D, S, T, ST, SYM, VS, VT>;
}

Represents any entity that participates in a causal context graph.

This trait defines the unified interface over any entity that may be:

• A data node
• A spatial or temporal marker
• A symbolic atom
• A spacetime event

It is designed to abstract over the underlying causal semantics while retaining compile-time type safety and minimal trait bounds.

Type Parameters

• D: A Datable node (e.g., sensor reading, fact, entity)
• S: A Spatial node
• T: A Temporal node
• ST: A SpaceTemporal node (4D entity)
• SYM: A Symbolic node (logical/abstract)
• VS: The numeric or symbolic coordinate type
• VT: The numeric or symbolic time type

Design Note

This trait is the dispatch point for ContextoidType, allowing static or dynamic graph traversal based on node kind. It intentionally generalizes over all possible causal node roles.

Required Methods

fn vertex_type(&self) -> &ContextoidType<D, S, T, ST, SYM, VS, VT>

Returns a reference to the type-erased node variant.

Use this to determine the role of the current node (data, space, time, etc.) and then downcast or dispatch accordingly.
