Module preflight 

Per-client admission before any backend request.

Structs

GuardedApi

Backend dispatch with a clone-shared client admission hook. The raw transport is private so a caller cannot skip admission through this value.

PreflightError

A request failed before its target was sent. A later operation may retry.

Traits

ConfigurationFetch

Restricted access to the credential-free configuration RPC. The hook cannot use this capability to send the operation it is checking.

RequestPreflight

Functions

failure

Find the admission marker without treating a failed configuration RPC as a failed target RPC. Explicitly unwrap boxes that hide their inner source.
