Overview ¶
Package async provides unbounded channel data structures that are designed for caching unlimited number of a concrete type. For better performance, a given type should be less or euqal than 16 bytes.
Delicate dance: One must aware that an unbounded channel may lead to OOM when the consuming speed of the buffer is lower than the producing speed constantly. However, such a channel may be fairly used for event delivering if the consumer of the channel consumes the incoming forever, such as even processing.
One must close such a channel via Close() method, closing the input channel via close() built-in method can leads to memory leak.
To support a new type, one may add the required data in the gen.go, for instances:
types := map[string]data{
"fyne_canvasobject.go": data{
Type: "fyne.CanvasObject",
Name: "CanvasObject",
Imports: `import "github.com/Jaeel/fyne"`,
},
"func.go": data{
Type: "func()",
Name: "Func",
Imports: "",
},
}
then run: `go generate ./...` to generate more desired unbounded channels.

Types ¶
type UnboundedCanvasObjectChan ¶
type UnboundedCanvasObjectChan struct {
// contains filtered or unexported fields
}
UnboundedCanvasObjectChan is a channel with an unbounded buffer for caching CanvasObject objects.
func NewUnboundedCanvasObjectChan ¶
func NewUnboundedCanvasObjectChan() *UnboundedCanvasObjectChan
NewUnboundedCanvasObjectChan returns a unbounded channel with unlimited capacity.
func (*UnboundedCanvasObjectChan) Close ¶
func (ch *UnboundedCanvasObjectChan) Close()
Close closes the channel.
func (*UnboundedCanvasObjectChan) In ¶
func (ch *UnboundedCanvasObjectChan) In() chan<- fyne.CanvasObject
In returns the send channel of the given channel, which can be used to send values to the channel.
func (*UnboundedCanvasObjectChan) Out ¶
func (ch *UnboundedCanvasObjectChan) Out() <-chan fyne.CanvasObject
Out returns the receive channel of the given channel, which can be used to receive values from the channel.
type UnboundedFuncChan ¶
type UnboundedFuncChan struct {
// contains filtered or unexported fields
}
UnboundedFuncChan is a channel with an unbounded buffer for caching Func objects.
func NewUnboundedFuncChan ¶
func NewUnboundedFuncChan() *UnboundedFuncChan
NewUnboundedFuncChan returns a unbounded channel with unlimited capacity.
func (*UnboundedFuncChan) In ¶
func (ch *UnboundedFuncChan) In() chan<- func()
In returns the send channel of the given channel, which can be used to send values to the channel.
func (*UnboundedFuncChan) Out ¶
func (ch *UnboundedFuncChan) Out() <-chan func()
Out returns the receive channel of the given channel, which can be used to receive values from the channel.
type UnboundedInterfaceChan ¶
type UnboundedInterfaceChan struct {
// contains filtered or unexported fields
}
UnboundedInterfaceChan is a channel with an unbounded buffer for caching Interface objects.
func NewUnboundedInterfaceChan ¶
func NewUnboundedInterfaceChan() *UnboundedInterfaceChan
NewUnboundedInterfaceChan returns a unbounded channel with unlimited capacity.
func (*UnboundedInterfaceChan) Close ¶
func (ch *UnboundedInterfaceChan) Close()
Close closes the channel.
func (*UnboundedInterfaceChan) In ¶
func (ch *UnboundedInterfaceChan) In() chan<- interface{}
In returns the send channel of the given channel, which can be used to send values to the channel.
func (*UnboundedInterfaceChan) Out ¶
func (ch *UnboundedInterfaceChan) Out() <-chan interface{}
Out returns the receive channel of the given channel, which can be used to receive values from the channel.
type UnboundedStructChan ¶
type UnboundedStructChan struct {
// contains filtered or unexported fields
}
UnboundedStructChan is a channel with an unbounded buffer for caching struct{} objects. This implementation is a specialized version that optimizes for struct{} objects than other types.
Delicate dance: One must aware that an unbounded channel may lead to OOM when the consuming speed of the buffer is lower than the producing speed constantly. However, such a channel may be fairly used for event delivering if the consumer of the channel consumes the incoming forever. Especially, rendering and even processing tasks.
func NewUnboundedStructChan ¶
func NewUnboundedStructChan() *UnboundedStructChan
NewUnboundedStructChan returns a unbounded channel with unlimited capacity.
func (*UnboundedStructChan) Close ¶
func (ch *UnboundedStructChan) Close()
Close closes the channel.
func (*UnboundedStructChan) In ¶
func (ch *UnboundedStructChan) In() chan<- struct{}
In returns a send-only channel that can be used to send values to the channel.
func (*UnboundedStructChan) Out ¶
func (ch *UnboundedStructChan) Out() <-chan struct{}
Out returns a receive-only channel that can be used to receive values from the channel.
