/**

 *
 * Validate the body of a request against a [StandardSchema](https://standardschema.dev/) or `Structure`.
 * This will throw nice {@link HTTPError} errors that are caught by gruber and sent along to the user.
 *
 * ```js
 * const struct = Structure.object({ name: Structure.string() })
 *
 * const body1 = await assertRequestBody(struct, new Request('…'))
 * ```
 *
 * > **NOTE** — you need to await the function when passing a `Request`
 *
 * or from a JavaScript value:
 *
 * ```js
 * const body2 = assertRequestBody(struct, { … })
 * const body3 = assertRequestBody(struct, new FormData(…))
 * const body3 = assertRequestBody(struct, new URLSearchParams(…))
 * ```
 *
 * you can use any StandardSchema library with this:
 *
 * ```js
 * import { z } from 'zod'
 *
 * const body4 = assertRequestBody(
 *   z.object({ name: z.string() }),
 *   { name: "Geoff Testington" }
 * )
 * ```
