Types

type Chan

type Chan chan struct{}

Chan is a simple notification channel

func (Chan) ReadOnly

func (c Chan) ReadOnly() ReadChan

ReadOnly converts c to receive-only channel

func (Chan) Receive

func (c Chan) Receive()

Receive receives a notification from channel. It blocks if channel is empty.

func (Chan) Send

func (c Chan) Send()

Send sends a notification to channel. It blocks if channel is full.

func (Chan) TryReceive

func (c Chan) TryReceive() bool

TryReceive receives a notification from channel. It returns false if channel is empty.

func (Chan) TrySend

func (c Chan) TrySend() bool

TrySend sends a notification to channel. It returns false if channel is full.

func (Chan) WriteOnly

func (c Chan) WriteOnly() WriteChan

WriteOnly converts c to send-only channel
