*
* The optional `options.statCheck` function may be specified to give user code

* of the given file:
*
* If an error occurs while attempting to read the file data, the `Http2Stream` will be closed using an `RST_STREAM` frame using the standard `INTERNAL_ERROR` code. If the `onError` callback is

* ```js
* const http2 = require('node:http2');
* const server = http2.createServer();
* server.on('stream', (stream) => {
* function statCheck(stat, headers) {

* // stream.respond() can throw if the stream has been destroyed by

* try {
* if (err.code === 'ENOENT') {
* stream.respond({ ':status': 404 });
* } else {
* stream.respond({ ':status': 500 });

* stream.end();
* }
*
* stream.respondWithFile('/some/file',
* { 'content-type': 'text/plain; charset=utf-8' },
* { statCheck, onError });
* });
* ```
*
* The `options.statCheck` function may also be used to cancel the send operation
* by returning `false`. For instance, a conditional request may check the stat
* results to determine if the file has been modified to return an appropriate `304` response:
*
* ```js
* const http2 = require('node:http2');
* const server = http2.createServer();
* server.on('stream', (stream) => {
* function statCheck(stat, headers) {
* // Check the stat here...

* return false; // Cancel the send operation
* }
* stream.respondWithFile('/some/file',
* { 'content-type': 'text/plain; charset=utf-8' },
* { statCheck });
* });
* ```
*
* The `content-length` header field will be automatically set.
*
* The `offset` and `length` options may be used to limit the response to a
* specific range subset. This can be used, for instance, to support HTTP Range
* requests.
*
* The `options.onError` function may also be used to handle all the errors
* that could happen before the delivery of the file is initiated. The
* default behavior is to destroy the stream.
*
* When the `options.waitForTrailers` option is set, the `'wantTrailers'` event
* will be emitted immediately after queuing the last chunk of payload data to be
* sent. The `http2stream.sendTrailers()` method can then be used to sent trailing

/**
* For HTTP/2 Client `Http2Session` instances only, the `http2session.request()` creates and returns an `Http2Stream` instance that can be used to send an
* HTTP/2 request to the connected server.
*
* When a `ClientHttp2Session` is first created, the socket may not yet be
* connected. if `clienthttp2session.request()` is called during this time, the
* actual request will be deferred until the socket is ready to go.
* If the `session` is closed before the actual request be executed, an `ERR_HTTP2_GOAWAY_SESSION` is thrown.
*
* This method is only available if `http2session.type` is equal to `http2.constants.NGHTTP2_SESSION_CLIENT`.
*
* ```js
* const http2 = require('node:http2');
* const clientSession = http2.connect('https://localhost:1234');
* const {
* HTTP2_HEADER_PATH,
* HTTP2_HEADER_STATUS,
* } = http2.constants;
*
* const req = clientSession.request({ [HTTP2_HEADER_PATH]: '/' });
* req.on('response', (headers) => {
* console.log(headers[HTTP2_HEADER_STATUS]);
* req.on('data', (chunk) => { // .. });
* req.on('end', () => { // .. });
* });
* ```
*
* When the `options.waitForTrailers` option is set, the `'wantTrailers'` event
* is emitted immediately after queuing the last chunk of payload data to be sent.
* The `http2stream.sendTrailers()` method can then be called to send trailing
* headers to the peer.
*
* When `options.waitForTrailers` is set, the `Http2Stream` will not automatically
* close when the final `DATA` frame is transmitted. User code must call either`http2stream.sendTrailers()` or `http2stream.close()` to close the`Http2Stream`.
*
* When `options.signal` is set with an `AbortSignal` and then `abort` on the
* corresponding `AbortController` is called, the request will emit an `'error'`event with an `AbortError` error.
*
* The `:method` and `:path` pseudo-headers are not specified within `headers`,
* they respectively default to:
*
* * `:method` \= `'GET'`
* * `:path` \= `/`
* @since v8.4.0
