Functions

func NewIMAPWorker 

func NewIMAPWorker(worker *types.Worker) (types.Backend, error)

Types

type CachedHeader 

type CachedHeader struct {
	BodyStructure models.BodyStructure
	Envelope      models.Envelope
	InternalDate  time.Time
	Uid           models.UID
	Size          uint32
	Header        []byte
	Created       time.Time
	Labels        []string
}

type ExpungeHandler 

type ExpungeHandler struct {
	// contains filtered or unexported fields
}

func NewExpungeHandler 

func NewExpungeHandler(worker *IMAPWorker, uids []uint32, forDelete bool) *ExpungeHandler

Create a new ExpungeHandler for a list of UIDs that are being deleted or moved.

func (*ExpungeHandler) IsExpungingForDelete 

func (h *ExpungeHandler) IsExpungingForDelete(uid uint32) bool

func (*ExpungeHandler) PopSequenceNumber 

func (h *ExpungeHandler) PopSequenceNumber(seqNum uint32) (uint32, bool)

Translate the sequence number received from the IMAP server into the associated UID, deduce the policy used by the server from the first reply, and update the remaining mappings according to that policy if required.

type IMAPWorker 

type IMAPWorker struct {
	// contains filtered or unexported fields
}

func (*IMAPWorker) BuildExpungeHandler 

func (w *IMAPWorker) BuildExpungeHandler(uids []uint32, forDelete bool)

func (*IMAPWorker) Capabilities 

func (w *IMAPWorker) Capabilities() *models.Capabilities

func (*IMAPWorker) PathSeparator 

func (w *IMAPWorker) PathSeparator() string

func (*IMAPWorker) Run 

func (w *IMAPWorker) Run()

type SeqMap 

type SeqMap struct {
	// contains filtered or unexported fields
}

func (*SeqMap) Get 

func (s *SeqMap) Get(seqnum uint32) (uint32, bool)

Get returns the UID of the given seqnum

func (*SeqMap) Initialize 

func (s *SeqMap) Initialize(uids []uint32)

Initialize sets the initial seqmap of the mailbox

func (*SeqMap) Pop 

func (s *SeqMap) Pop(seqnum uint32) (uint32, bool)

Pop removes seqnum from the SeqMap. seqnum must be a valid seqnum, ie [1:size of mailbox]

func (*SeqMap) Put 

func (s *SeqMap) Put(uid uint32)

Put adds a UID to the slice. Put should only be used to add new messages into the slice

func (*SeqMap) Size 

func (s *SeqMap) Size() int

func (*SeqMap) Snapshot 

func (s *SeqMap) Snapshot(uids []uint32) (map[uint32]uint32, uint32)

Take a snapshot of the SequenceNumber=>UID mappings for the given UIDs, remove those UIDs from the SeqMap, and return the snapshot it to the caller, as well as the loweest sequence number it contains.
