class TestThreadSampler
Defined at line 34 of file ../../zircon/kernel/lib/thread_sampler/tests/thread_sampler_tests.cc
A test version of ThreadSampler which overrides functions
for testing purposes.
Despite having a test class, we use the global sampler::gThreadSampler for tests. The timer
callbacks sampling sets assume a static lifetime for the sampler.
