Types

type Availability added in v0.14.12 

type Availability struct {
	ID            protocol.DeviceID `json:"id"`
	FromTemporary bool              `json:"fromTemporary"`
}

type ConnectionInfo 

type ConnectionInfo struct {
	protocol.Statistics
	Connected     bool
	Paused        bool
	Address       string
	ClientVersion string
	Type          string
}

func (ConnectionInfo) MarshalJSON 

func (info ConnectionInfo) MarshalJSON() ([]byte, error)

type FolderCompletion added in v0.14.12 

type FolderCompletion struct {
	CompletionPct float64
	NeedBytes     int64
	GlobalBytes   int64
	NeedDeletes   int64
}

type Holdable added in v0.14.12 

type Holdable interface {
	Holders() string
}

type IndexSorter added in v0.14.12 

type IndexSorter interface {
	Append(f protocol.FileInfo)
