  StringWriter,
} from "https://deno.land/std@0.224.0/io/mod.ts";
import { copy } from "https://deno.land/std@0.224.0/streams/copy.ts";

const w = new StringWriter("base");
const r = new StringReader("0123456789");
await copyN(r, w, 4); // copy 4 bytes

// Number of bytes read
console.log(w.toString()); //base0123
