func (fh *FileHandler) SHA256() string

SHA256 hash of the handled file

type PreAuthorizer

type PreAuthorizer interface {
	PreAuthorizeHandler(next api.HandleFunc, suffix string) http.Handler
}

	// PresignedCompleteMultipart is a presigned URL for CompleteMulipartUpload
	PresignedCompleteMultipart string
	// PresignedAbortMultipart is a presigned URL for AbortMultipartUpload
	PresignedAbortMultipart string
}

SaveFileOpts represents all the options available for saving a file to object store
