There was a problem hiding this comment.
suggestion: Could we avoid in-band errors here and return multiple values?
maybe:
func (s *SourceManager) AvailableCapacity() (int, bool) {
if s.poolLimit == 0 {
return 0, false
}
runCount := atomic.LoadInt32(&s.currentRunningCount)
return s.poolLimit - int(runCount), true
}
