func (*FileWatcher) Scan

func (f *FileWatcher) Scan() ([]string, bool, error)

Scan scans all file paths and checks if the number of files or the modtime of the files changed It returns the list of existing files, a boolean if anything in has changed and potential errors. To detect changes not only modtime is compared but also the hash of the files list. This is required to also detect files which were removed. Normally, the modtime is presented in seconds, so the change detection is also based on seconds. When it's unclear whether something changed or not the method will return `true` to make sure potential changes are handled. It is strongly recommended to call `Scan` not more than once a second.
