// This header is intended to be used only for api_integrationtest.cc and solves
// the following problem: api_integrationtest.cc doesn't pull any non-public
// perfetto header, to spot accidental public->non-public dependencies.
// Sometimes, however, we need to use some internal perfetto code for the test
// itself. This header exposes wrapper functions to achieve that without leaking
// internal headers.

//  IMPORTANT: This header must not pull any non-public perfetto header.
