Types ¶
type MultiWriter ¶ added in v0.0.21
type MultiWriter struct {
Writer
// contains filtered or unexported fields
}
Type MultiWriter holds mutltiple Writer instances.
func (*MultiWriter) Close ¶ added in v0.0.21
func (mw *MultiWriter) Close(ctx context.Context) error
func (*MultiWriter) WriteFeature ¶ added in v0.0.21

type StdoutWriter ¶
type StdoutWriter struct {
Writer
}
func (*StdoutWriter) Close ¶ added in v0.0.16
func (wr *StdoutWriter) Close(ctx context.Context) error
func (*StdoutWriter) WriteFeature ¶
func (wr *StdoutWriter) WriteFeature(ctx context.Context, uri string, f *geotag.GeotagFeature) error
type Writer ¶
type Writer interface {
WriteFeature(context.Context, string, *geotag.GeotagFeature) error
Close(context.Context) error
}
func NewIOWriter ¶ added in v0.0.12
func NewMultiWriter ¶ added in v0.0.21
NewMultiWriter returns a Writer instance that will send all writes to each instance in 'writers'. Writes happen synchronolously in the order in which the underlying Writer instances are specified.
