Crate seatbelt_http 

HTTP-specific extensions for the seatbelt resilience middleware.

Each seatbelt middleware is generic over its input and output types. This crate specializes them for HttpRequest / Result<HttpResponse> 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: classifies HTTP responses as recoverable. By default, 5xx status codes, 429 Too Many Requests, and request timeouts are treated as transient.
• HttpClone: selects which HTTP methods are eligible for cloning during retries and hedging (safe-only, idempotent, or all).
• HttpResilienceContext: the HTTP specialization of ResilienceContext.
