Module http 

Service-agnostic HTTP core: the transport probe behind grr transport, and the request-execution engine (execute plus the verb builders) it hosts.

Zero-config by construction: all tuning is compile-time constants. tokio sizes OS threads to cores; the semaphore bounds only in-flight HTTP requests so bursts stay under Google’s per-user rate limits.

Structs

HttpCore

The authenticated HTTP engine. HttpCore::connect negotiates the transport version against a service base URL and records it in TransportInfo; grr transport reports that result.

TransportInfo

Enums

TransportMode

Functions

apply_transport_version

Apply the transport-level HTTP version override for data-plane requests.

build_http_client

Build HTTP client with auto-tuned transport settings.

resolve_transport_mode

The transport a client is built for: HTTP/3 where it is requested, HTTP/2 prior knowledge on the fallback path HttpCore::connect takes when the HTTP/3 probe fails. Both call sites go through here so the mode is chosen in exactly one place.
