Types

type BeginFrameParams

type BeginFrameParams struct {
	FrameTime        *runtime.Timestamp `json:"frameTime,omitempty"`        // Timestamp of this BeginFrame (milliseconds since epoch). If not set, the current time will be used.
	Deadline         *runtime.Timestamp `json:"deadline,omitempty"`         // Deadline of this BeginFrame (milliseconds since epoch). If not set, the deadline will be calculated from the frameTime and interval.
	Interval         float64            `json:"interval,omitempty"`         // The interval between BeginFrames that is reported to the compositor, in milliseconds. Defaults to a 60 frames/second interval, i.e. about 16.666 milliseconds.
	NoDisplayUpdates bool               `json:"noDisplayUpdates,omitempty"` // Whether updates should not be committed and drawn onto the display. False by default. If true, only side effects of the BeginFrame will be run, such as layout and animations, but any visual updates may not be visible on the display or in screenshots.
	Screenshot       *ScreenshotParams  `json:"screenshot,omitempty"`       // If set, a screenshot of the frame will be captured and returned in the response. Otherwise, no screenshot will be captured.
}

BeginFrameParams sends a BeginFrame to the target and returns when the frame was completed. Optionally captures a screenshot from the resulting frame. Requires that the target was created with enabled BeginFrameControl.

func BeginFrame

func BeginFrame() *BeginFrameParams

BeginFrame sends a BeginFrame to the target and returns when the frame was completed. Optionally captures a screenshot from the resulting frame. Requires that the target was created with enabled BeginFrameControl.

parameters:

func (*BeginFrameParams) Do

func (p *BeginFrameParams) Do(ctxt context.Context, h cdp.Executor) (hasDamage bool, mainFrameContentUpdated bool, screenshotData []byte, err error)

Do executes HeadlessExperimental.beginFrame against the provided context.

returns:

hasDamage - Whether the BeginFrame resulted in damage and, thus, a new frame was committed to the display.
mainFrameContentUpdated - Whether the main frame submitted a new display frame in response to this BeginFrame.
screenshotData - Base64-encoded image data of the screenshot, if one was requested and successfully taken.

func (BeginFrameParams) WithDeadline

func (p BeginFrameParams) WithDeadline(deadline *runtime.Timestamp) *BeginFrameParams

func (BeginFrameParams) WithScreenshot

func (p BeginFrameParams) WithScreenshot(screenshot *ScreenshotParams) *BeginFrameParams
