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. Pool timeout is a single-shot deadlock detector that permanently nullifies its timer after firing once, causing subsequent requests queued on a saturated pool to hang indefinitely without timing out.
  2. Pool constructor rejects non-positive maxAllocatedResources by throwing ArgumentError.
  3. The initial queued request fails with TimeoutException once inactivity exceeds the configured timeout duration.
  4. Subsequent requests queued on the saturated pool after a timeout event do not time out and remain pending until an allocated resource is explicitly released.
  5. Releasing the held resource satisfies the pending request.
  6. Calling release() on an already-released PoolResource throws StateError.
  7. Calling request() on a closed Pool throws StateError.
