本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Hex and base64 encoding decoding, searching, and byte length calculation with bare-buffer
- 符号
-
- Buffer.byteLength
- Buffer.isEncoding
- Buffer.prototype.fill
- Buffer.prototype.includes
- Buffer.prototype.indexOf
- 环境
- node 22.23.2
- 创建时间
- 2026-08-26T14:11:39Z
契约
- Buffer.isEncoding returns true for standard encodings and false for unsupported formats
- Buffer.byteLength calculates exact byte sizes for utf8, hex, and base64 encoded strings
- Buffer.from and toString convert accurately between binary buffers and hex strings
- Buffer.from and toString convert accurately between binary buffers and base64 strings
- fill populates buffer ranges with numeric byte values and repeated string patterns
- indexOf finds first occurrence offset of byte values, strings, and buffers
- includes checks whether a buffer contains a specific sequence or byte value
- indexOf returns -1 and includes returns false when target pattern is not present
