Trait ContextEnricher

    // Required methods
    fn name(&self) -> &str;
    fn enrich(&self, fib_entry: Option<&FibEntry>, extensions: &mut AnyMap);
}

Populates cross-layer data in the strategy context extensions.

Implementations pull from whatever data source they own (RadioTable, FlowTable, GPS receiver, battery monitor, …) and insert a DTO into the AnyMap. StrategyStage holds a Vec<Arc<dyn ContextEnricher>> and calls each one before every strategy invocation.

Adding a new data source

1. Define a DTO struct (e.g. LocationSnapshot) in ndn-strategy::cross_layer.
2. Implement ContextEnricher — read your data source, build the DTO, call extensions.insert(dto).
3. Register via EngineBuilder::context_enricher(Arc::new(YourEnricher { ... })).

No changes to StrategyContext, StrategyStage, or existing enrichers are needed.

Required Methods

fn name(&self) -> &str

Human-readable name (for logging / debug).

fn enrich(&self, fib_entry: Option<&FibEntry>, extensions: &mut AnyMap)

Insert zero or more typed values into extensions.
