|
* ```ts

* import { StringReader } from "https://deno.land/std@$STD_VERSION/io/string_reader.ts";
|
|
*
|
|
* const data = new Uint8Array(6);

|
* const res0 = await r.read(data);

|
* const res1 = await r.read(new Uint8Array(6));
|
|
*
|
|
* // Number of bytes read
|
|
* console.log(res0); // 6
|
|
* console.log(res1); // null, no byte left to read. EOL
|
|
*
|
|
* // text
|
|
*
|
|
* console.log(new TextDecoder().decode(data)); // abcdef
|
