So, for instance, this appears to compile, but I haven't run it yet:
func getFromCommitsCache[T any](project string, repo string, branch string)
([]T, bool) {
commitsCacheMutex.RLock()
defer commitsCacheMutex.RUnlock()
var result []T
if commits, found := commitsCache[project+"/"+repo+"/"+branch]; found {
for _, commit := range commits {
result = append(result, commit.(T))
}
return result, true
}
return nil, false
}
func storeToCommitsCache[T any](project string, repo string, branch string,
commits []T) {
commitsCacheMutex.Lock()
defer commitsCacheMutex.Unlock()
var anyResult []any
for _, commit := range commits {
anyResult = append(anyResult, commit)
}
commitsCache[project+"/"+repo+"/"+branch] = anyResult
}
