conformance.proto

// Vendored from https://github.com/protocolbuffers/protobuf/blob/main/conformance/conformance.proto
//
// This is the wire protocol the upstream conformance_test_runner
// uses to drive any test program. Each test sends one
// ConformanceRequest over stdin and expects one ConformanceResponse
// back over stdout. See the upstream README for the runner's
// command-line interface and the test categories it covers.
//
// We pull this in with loadProto in
// `Test.Conformance.RunnerInstances` so the runner binary's
// codecs come from the same machinery the rest of wireform-proto
// uses (and consequently a regression in the deriver shows up
// immediately as a conformance-suite mismatch).
