}

Config is a file uploader configuration

func (*Config) CheckAndSetDefaults

func (s *Config) CheckAndSetDefaults() error

CheckAndSetDefaults checks and sets default values of file handler config

type Handler

type Handler struct {
	// Config is a file sessions config
	Config
	// Entry is a file entry
	*log.Entry
}

Handler uploads and downloads sessions archives by reading and writing files to directory, useful for NFS setups and tests

type ScanStats

type ScanStats struct {
	// Scanned is how many uploads have been scanned
	Scanned int
	// Started is how many uploads have been started
	Started int
}
