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. anypb.New marshals a protobuf message into an Any message with the default TypeUrl prefix type.googleapis.com/ followed by the full message name, while anypb.New(nil) returns an error.
  2. any.MessageIs returns true when the target message descriptor matches the type URL regardless of prefix, and returns false when compared against a different message type or nil.
  3. any.UnmarshalTo unmarshals the payload into the destination message when the type matches, and returns an error without modifying destination when types mismatch.
  4. any.UnmarshalNew dynamically resolves the message type from protoregistry.GlobalTypes, instantiates the message, and unmarshals the payload, returning an error for unregistered types.
  5. anypb.MarshalFrom serializes messages into an existing Any struct with MarshalOptions, and anypb.UnmarshalNew supports custom protoregistry.Types resolvers via UnmarshalOptions.
