よくある思い込み
Bun binary APIs receive a typed array's entire backing ArrayBuffer, so passing a subarray with a non-zero offset hashes, compresses, or writes bytes outside the view.
このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。
コントラクト
- Bun.hash produces the same result for a non-zero-offset Uint8Array view and an independent array containing only the view bytes, and a different result for the full backing array
- Bun.SHA256.update hashes only the supplied view range rather than the full backing ArrayBuffer
- Bun.gzipSync followed by Bun.gunzipSync preserves exactly the view bytes
- Bun.write persists exactly the view bytes and excludes the prefix and suffix in the backing array
