Per-connection state for TCP filters.

Fields

remote_addr: &'a str

Remote client address.

local_addr: &'a str

Local listener address.

sni: Option<&'a str>

SNI hostname extracted from the TLS ClientHello, if present.

upstream_addr: Option<Cow<'a, str>>

Upstream address being proxied to.

None until a static upstream or a filter (e.g. sni_router) provides one.

cluster: Option<Arc<str>>

Cluster name selected for this connection.

Set by the listener config when cluster is configured. Read by tcp_load_balancer to look up the strategy.

health_registry: Option<&'a HealthRegistry>

Shared health registry for endpoint health lookups.

kv_stores: Option<&'a KvStoreRegistry>

Named key-value stores for runtime mappings.

connect_time: Instant

When the connection was accepted.

bytes_in: u64

Bytes received from client (populated after forwarding completes).

bytes_out: u64

Bytes sent to client (populated after forwarding completes).
