+
+HTTP-specific extensions for the [`seatbelt`][__link0] resilience middleware.
+
+Each [`seatbelt`][__link1] middleware is generic over its input and output types.
+This crate specializes them for [`HttpRequest`][__link2] /
+[`Result<HttpResponse>`][__link3] and adds HTTP-aware
+builder methods, all prefixed with `http_`.
+
+## Supported middleware
+
+Each middleware lives in its own feature-gated module with specialized
+type aliases and an extension trait:
+
+|Module|Feature|Purpose|
+|------|-------|-------|
+|`retry`|`retry`|Recovery classification, request cloning, request restoration from errors.|
+|`timeout`|`timeout`|Converts timeout events into HTTP-specific errors.|
+|`hedging`|`hedging`|Recovery classification and request cloning for tail-latency reduction.|
+|`breaker`|`breaker`|Recovery classification and rejected-request error handling.|
+
+## Shared types
+
+* [`HttpRecovery`][__link4]: classifies HTTP responses as recoverable. By default,
+  5xx status codes, `429 Too Many Requests`, and request timeouts are
+  treated as transient.
+* [`HttpClone`][__link5]: selects which HTTP methods are eligible for cloning
+  during retries and hedging (safe-only, idempotent, or all).
+* [`HttpResilienceContext`][__link6]: the HTTP specialization of
+  [`ResilienceContext`][__link7].
