Struct ComposedStrategy 

pub struct ComposedStrategy { /* private fields */ }

A strategy that delegates to an inner strategy and post-processes its forwarding actions through a chain of filters.

This enables cross-layer filtering without modifying base strategies. For example, composing BestRouteStrategy with an RssiFilter produces “best-route but only on faces with acceptable signal strength.”

Implementations

impl ComposedStrategy

pub fn new( name: Name, inner: Arc<dyn ErasedStrategy>, filters: Vec<Arc<dyn StrategyFilter>>, ) -> Self

Build a composed strategy from an inner strategy and an ordered filter chain.

Trait Implementations

impl ErasedStrategy for ComposedStrategy

fn name(&self) -> &Name

Canonical name identifying this strategy (e.g. /localhost/nfd/strategy/best-route).

fn decide_sync( &self, ctx: &StrategyContext<'_>, ) -> Option<SmallVec<[ForwardingAction; 2]>>

Synchronous fast path — avoids the Box::pin heap allocation. Returns None to fall through to the async path.

fn after_receive_interest_erased<'a>( &'a self, ctx: &'a StrategyContext<'a>, ) -> Pin<Box<dyn Future<Output = SmallVec<[ForwardingAction; 2]>> + Send + 'a>>

Async path for Interest forwarding decisions (boxed future).

fn on_nack_erased<'a>( &'a self, ctx: &'a StrategyContext<'a>, reason: NackReason, ) -> Pin<Box<dyn Future<Output = ForwardingAction> + Send + 'a>>

Handle an incoming Nack and decide whether to retry or propagate.
