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. assert set(key, undefined) silently deletes entry rather than storing undefined value like Map.set
  2. assert legacy v6 options maxAge and length are silently ignored in constructor and set() without error or effect
  3. assert overwriting an existing key triggers dispose with reason set unless noDisposeOnSet is configured
  4. assert fetchMethod rejection deletes existing stale entry from cache unless allowStaleOnFetchRejection is enabled
  5. assert iteration orders keys from MRU to LRU and get() updates MRU position while peek() preserves ordering
