Calling write() on a closed FileSink throws an error or rejects, just like writing to a closed stream in Node.js or web streams.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

const file = Bun.file('data.bin');
const writer = file.writer();
writer.end();
const res = writer.write('A');
assert.strictEqual(res, true, 'write() on a closed FileSink returns true rather than throwing an error');
assert.strictEqual(await file.text(), '', 'Data written after end() is silently discarded');
