Revert "refactor(fetch): reimplement fetch with hyper instead of reqwest (#24237)" (#24574)
This reverts commit f6fd6619e7.

I'm seeing a difference between canary and 1.45.2. In
`deno-docs/reference_gen` I can't download dax when running `deno task
types`

```

deno_fetch

This crate implements the Fetch API.

Spec: https://fetch.spec.whatwg.org/

Usage Example

From javascript, include the extension's source, and assign the following properties to the global scope:

import * as headers from "ext:deno_fetch/20_headers.js";
import * as formData from "ext:deno_fetch/21_formdata.js";
import * as request from "ext:deno_fetch/23_request.js";
import * as response from "ext:deno_fetch/23_response.js";
import * as fetch from "ext:deno_fetch/26_fetch.js";
import * as eventSource from "ext:deno_fetch/27_eventsource.js";

// Set up the callback for Wasm streaming ops
Deno.core.setWasmStreamingCallback(fetch.handleWasmStreaming);

Object.defineProperty(globalThis, "fetch", {
  value: fetch.fetch,
  enumerable: true,
  configurable: true,
  writable: true,
});

Object.defineProperty(globalThis, "Request", {
  value: request.Request,
  enumerable: false,
  configurable: true,
  writable: true,
});

Object.defineProperty(globalThis, "Response", {
  value: response.Response,
  enumerable: false,
  configurable: true,
  writable: true,
});

Object.defineProperty(globalThis, "Headers", {
  value: headers.Headers,
  enumerable: false,
  configurable: true,
  writable: true,
});

Object.defineProperty(globalThis, "FormData", {
  value: formData.FormData,
  enumerable: false,
  configurable: true,
  writable: true,
});

Then from rust, provide deno_fetch::deno_fetch::init_ops_and_esm<Permissions>(Default::default()) in the extensions field of your RuntimeOptions

Where:

  • Permissions: a struct implementing deno_fetch::FetchPermissions
  • Options: deno_fetch::Options, which implements Default

  • deno_web: Provided by the deno_web crate
  • deno_url: Provided by the deno_url crate
