Functions

func Handler

func Handler(o interface{}, filePrefix string, logger Logger) http.Handler

Handler returns http.Handler that will call DataDump on every o field that implements Interface. If filePrefix is not blank Content-Disposition HTTP header will be added to the response. The response body will be the tar archive containing binary files named by the o fields that implement Interface. The provided interface can be a struct or a map with string keys and interface{} values that will be checked if they implement the Interface.

Types

type Dump

type Dump struct {
	Name        string
	ContentType string
	Length      int64
	ModTime     *time.Time
	Body        io.ReadCloser
}

Dump defines a structure that holds dump metadata and body as reader interface. Body must be closed after the read is done.

type Interface

type Interface interface {
	DataDump(ifModifiedSince *time.Time) (dump *Dump, err error)
}

Interface defines method to retrieve data Dump. If ifModifiedSince is not nil and data is not changed since provided time, both return values, Dump and error, will be nil.
