alpaca-rest-http

alpaca-rest-http provides the shared transport layer for the alpaca-rust workspace.

It exposes request construction, retry policy, response metadata, observer hooks, and concurrency limiting. Most application code should use alpaca-data or alpaca-trade instead of depending on this crate directly.

Core pieces:

• HttpClient
• HttpClientBuilder
• RetryConfig
• TransportObserver
• RequestParts
• ResponseMeta

What this crate is for:

• low-level HTTP client reuse across alpaca-data, alpaca-trade, and alpaca-mock
• retry, backoff, error metadata, and request observer wiring
• generic request execution against configurable base URLs

What this crate is not for:

• Alpaca resource semantics
• typed market-data or trading models
• cache or subscription systems
• application lifecycle management
