/**
 * A typed accessor for a Cloudflare Hyperdrive runtime binding inside a
 * Worker. Provides the same shape as the raw `Hyperdrive` runtime object
 * (connection string, host, port, user, password, database) plus a `raw`
 * escape hatch for libraries that want direct access.
 *
 * **Example:** Bind Hyperdrive in a Worker
 * ```typescript
 * const hd = yield* Cloudflare.Hyperdrive.Connect(MyConnection);
 * const url = yield* hd.connectionString;
 * ```
 *
 * @binding
 * @product Hyperdrive
 * @category Storage & Databases
