Crate ferryman 

ferryman — hyper-based reverse proxy service: the per-request handler (proxy), optional TLS termination (tls), and the hot-reload watcher (reload).

main.rs is a thin CLI wrapper around serve so integration tests can drive the same accept loop on an ephemeral port.

Modules

proxy

Per-request handler. Looks up the routing table, rebuilds the URI for the chosen upstream, streams the request straight through via the shared hyper client, records metrics, and turns transport failures into circuit-breaker trips.

reload

Filesystem-watch driven hot-reload of the routing table.

tls

Optional TLS termination.

Constants

LATENCY_BUCKETS

Latency buckets (seconds) for ferryman_request_duration_seconds, spanning sub-millisecond proxy hops up to upstream_timeout_secs’s default of 30s, so the slowest (about-to-time-out) requests still land in a real bucket instead of falling into +Inf.

Functions

serve

Accept connections on listener and serve the proxy until shutdown resolves, then stop accepting and wait (up to GRACEFUL_SHUTDOWN_TIMEOUT, 25s) for in-flight connections to finish.

Type Aliases

ProxyClient

Shared hyper client used to forward requests to upstreams. Bodies are streamed straight through (Incoming in, Incoming out), no buffering.
