std::counting_semaphore<LeastMaxValue>::try_acquire_until
Min standard notice:
Tries to atomically decrement the internal counter by 1 if it is greater than 0; otherwise blocks until it is greater than 0 and can successfully decrement the internal counter, or the abs_time time point has been passed.
# Declarations
template< class Clock, class Duration >
bool try_acquire_until( const std::chrono::time_point<Clock, Duration>& abs_time );
(since C++20)
# Parameters
abs_time: the earliest time the function must wait until in order to fail
# Return value
true if it decremented the internal counter, otherwise false.
# Notes
In practice the function may take longer than abs_time to fail.
