Struct Responder 

pub struct Responder { /* private fields */ }

Reply builder passed to producer handlers in [Producer::serve].

A Responder is a single-use object: call exactly one of [respond], [respond_bytes], or [nack] to send a reply. Dropping without calling a reply method silently discards the Interest.

Example

use ndn_packet::encode::DataBuilder;

producer.serve(|interest, responder| async move {
    let data = DataBuilder::new((*interest.name).clone(), b"hello").build();
    responder.respond_bytes(data).await.ok();
}).await

Implementations

impl Responder

pub async fn respond_bytes(self, wire: Bytes) -> Result<(), AppError>

Send a raw pre-encoded Data wire packet as the reply.

pub async fn respond( self, name: Name, content: impl Into<Bytes>, ) -> Result<(), AppError>

Build and send a Data packet with the given name and content.

pub async fn nack(self, reason: NackReason) -> Result<(), AppError>

Send a Nack reply for the Interest.

The Nack is encoded as an NDNLPv2 LpPacket containing the original Interest wire as the Fragment field, per NDNLPv2 §5.2.
