This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. ptypes.MarshalAny serializes a protobuf message into a google.protobuf.Any container with the expected type URL
  2. ptypes.Is accurately tests whether a google.protobuf.Any message matches a target protobuf message type
  3. ptypes.UnmarshalAny unpacks the encapsulated message payload from an Any container into the target message struct
  4. ptypes.UnmarshalAny returns an error when unmarshaling into a mismatched target message type
  5. ptypes.DynamicAny dynamically unmarshals an Any container without requiring a static message type target
