Module routing_port 

Routing superset — load-balancing strategies, circuit breakers, weighted fallback.

Pure types and selection logic live here (no I/O). Adapters such as routing-phenotype-router and the legacy omniroute-adapter wire these primitives to real providers.

Structs

CircuitBreaker

Per-target circuit breaker with lazy recovery on read.

CircuitBreakerConfig

Thresholds controlling circuit-breaker transitions.

FallbackEntry

One entry in an ordered fallback chain.

RoutingPoolState

Mutable routing pool state (cursors, counters, per-target health).

RoutingSelector

Pure selection helpers — deterministic given inputs and mutable state.

RoutingSuperset

Bundled routing superset: pool load-balancing with fallback chain and health tracking.

RoutingTarget

A routable engine/model target in a load-balanced pool.

SupersetRoutingDecision

A routing decision enriched with the chosen target id.

TargetHealth

Health and load counters for a single target.

Enums

CircuitState

Circuit breaker state for a single target.

RoutingStrategy

Load-balancing strategy over a pool of candidate targets.
