Module protocol_negotiator 

Protocol version and feature negotiation between peers.

When two IPFRS peers connect, they exchange ProtocolOffer messages to determine the best mutually supported configuration:

• The highest protocol version both sides understand
• The intersection of supported feature flags
• A safe chunk size (minimum of both peers’ preferences)

Example

use ipfrs_network::protocol_negotiator::{
    NegotiatorConfig, ProtocolFeature, ProtocolNegotiator, NegotiationResult,
};

let config = NegotiatorConfig::default();
let negotiator = ProtocolNegotiator::new(config);

let local = negotiator.config.local_offer(
    "local-peer".to_string(),
    vec![ProtocolFeature::Encryption, ProtocolFeature::Compression],
);
let remote = negotiator.config.local_offer(
    "remote-peer".to_string(),
    vec![ProtocolFeature::Encryption, ProtocolFeature::Multiplexing],
);

match negotiator.negotiate(&local, &remote) {
    NegotiationResult::Agreed { version, features, chunk_size } => {
        assert_eq!(version, 3);
        assert_eq!(features, vec![ProtocolFeature::Encryption]);
        assert_eq!(chunk_size, 65536);
    }
    other => panic!("unexpected result: {:?}", other),
}
