| # Library restrictions |
| |
| ## third_party/absl-cpp |
| |
| Decision: **do not use** `<absl/synchronization/*>`. On Fuchsia, these classes |
| bottom out in `pthread_mutex_t` and `pthread_cond_t`, which are not the most |
| efficient primitives on Fuchsia. When `ABSL_INTERNAL_USE_NONPROD_MUTEX` is |
| defined, these primitives bottom out in something much more sophisticated. |
| Instead, please use `<lib/sync/*.h>`, which bottoms out in optimal |
| synchronization primitives on Fuchsia. |
| |
| ## third_party/googletest |
| |
| *** aside |
| Note that the googletest library includes both the former gtest and gmock |
| projects. |
| *** |
| |
| Decision: **do not use** the mocking functionality of gmock (`MOCK_METHOD` and |
| `EXPECT_CALL`). It is allowed to use gmock matchers (such as `ElementsAre()`). |
