FlowKeyExtractor

sozu_lib::protocol::udp::manager

Trait FlowKeyExtractor 

Source 
pub trait FlowKeyExtractor {
    // Required method
    fn flow_key(
        &self,
        src: SocketAddr,
        payload: &[u8],
        cfg: &ClusterConfig,
    ) -> Option<FlowKey>;
}
Expand description

Extracts a FlowKey from an admitted client datagram. The default SourceTupleExtractor keys on the real client source address (2-tuple source-IP or 4-tuple source-IP+port per cluster config). The trait is the only seam for alternative keying (e.g. a QUIC-CID extractor, a non-goal); the 4-tuple impl is the only one in scope.

Required Methods§

Source

fn flow_key( &self, src: SocketAddr, payload: &[u8], cfg: &ClusterConfig, ) -> Option<FlowKey>

Compute the flow key for a datagram from src. Returns None to reject the datagram (the manager then emits Drop(Invalid) and allocates nothing). cfg is the listener’s active cluster config.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
