Types

type ActiveInfo 

type ActiveInfo struct {
	Name string
	Size int

}

type Bitfield 

type Bitfield = int

type Bridge 

type Bridge struct {

func (b *Bridge) Call(method string, arguments ...any) (result js.Value)

Call submits queued commands and invokes a context method directly.

func (*Bridge) DeleteResource 

func (b *Bridge) DeleteResource(id uint32)

RecordU32 appends a fixed-width command while a frame is recording.

func (*Bridge) RegisterResource 

func (b *Bridge) RegisterResource(value js.Value) (id uint32)

	OnContextRestored func()
	// contains filtered or unexported fields
