Deprecated
Use file.statSync() instead.
Deno.fstatSync will be removed in Deno 2.0.
Synchronously returns a Deno.FileInfo for the given file
stream.
import { assert } from "https://deno.land/std/assert/mod.ts";
const file = Deno.openSync("file.txt", { read: true });
const fileInfo = Deno.fstatSync(file.rid);
assert(fileInfo.isFile);
