Function retryFor
Retry the 'check' condition until it is true, or the timeout expires.
void retryFor
(
lazy bool check,
core
lazy string msg = "",
string file = __FILE__,
ulong line = cast(ulong)__LINE__
);
This is a test-only utility, as it will sleep the main thread for 100 msecs
between each re-try. Retry utilities should use TaskManager for
sleep as it will yield the task but not block the thread.
If the timeout expires, and the 'check' condition is still false, it throws an AssertError, which is an unrecoverable error.
