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。 MIT-0

契约

  1. UUIDv7 encodes Unix epoch milliseconds in its first 48 bits, ensuring generated UUIDs sort lexicographically in chronological order across millisecond timestamps
  2. UUIDv7 extracts the exact 48-bit big-endian millisecond timestamp passed via options.msecs
  3. UUIDv7 with identical timestamps sorts strictly by sequence number
  4. v1ToV6 reorders UUIDv1 timestamp fields into high-mid-low order into a valid UUIDv6 that sorts chronologically
  5. v6ToV1 losslessly restores the original UUIDv1 from a UUIDv6 representation
  6. v1ToV6 and v6ToV1 accept either formatted UUID strings or 16-byte Uint8Array buffers and return the matching representation
  7. v7 throws Error when provided with a random byte array shorter than 16 bytes
  8. v1ToV6 and v6ToV1 throw TypeError on invalid UUID strings
