Struct StrategyContext 

pub struct StrategyContext<'a> {
    pub name: &'a Arc<Name>,
    pub in_face: FaceId,
    pub fib_entry: Option<&'a FibEntry>,
    pub pit_token: Option<PitToken>,
    pub measurements: &'a MeasurementsTable,
    pub extensions: &'a AnyMap,
}

An immutable view of the engine state provided to strategy methods.

Strategies cannot mutate forwarding tables directly — they return ForwardingAction values and the pipeline runner acts on them.

Fields

name: &'a Arc<Name>

The name being forwarded.

in_face: FaceId

The face the Interest or Data arrived on.

fib_entry: Option<&'a FibEntry>

FIB entry for the longest matching prefix of name.

pit_token: Option<PitToken>

PIT token for the current Interest, if applicable.

measurements: &'a MeasurementsTable

Read-only access to EWMA measurements per (prefix, face).

extensions: &'a AnyMap

Cross-layer enrichment data (radio metrics, flow stats, etc.).

Populated by ContextEnricher instances before the strategy runs. Strategies access typed data via ctx.extensions.get::<T>().
