PitCheckStage

ndn_engine::stages::pit

Struct PitCheckStage 

Source 
pub struct PitCheckStage {
    pub pit: Arc<Pit>,
}
Expand description

Checks the PIT for a pending Interest.

Duplicate suppression: if the nonce has already been seen in the PIT entry, the Interest is a loop — drop it.

Aggregation: if a PIT entry already exists for the same (name, selector), add an in-record and return Action::Drop (the original forwarder already has an outstanding Interest; no need to forward again).

New entry: create a PIT entry, write ctx.pit_token, continue to StrategyStage.
