Types ¶
type EnableArgs ¶
type EnableArgs struct {
EventTypes []string `json:"eventTypes"` // The types of event to report, as specified in https://w3c.github.io/performance-timeline/#dom-performanceentry-entrytype The specified filter overrides any previous filters, passing empty filter disables recording. Note that not all types exposed to the web platform are currently supported.
}
EnableArgs represents the arguments for Enable in the PerformanceTimeline domain.
func NewEnableArgs ¶
func NewEnableArgs(eventTypes []string) *EnableArgs
NewEnableArgs initializes EnableArgs with the required arguments.
type LargestContentfulPaint ¶
type LargestContentfulPaint struct { RenderTime network.TimeSinceEpoch `json:"renderTime"` // No description. LoadTime network.TimeSinceEpoch `json:"loadTime"` // No description. Size float64 `json:"size"` // The number of pixels being painted. ElementID *string `json:"elementId,omitempty"` // The id attribute of the element, if available. URL *string `json:"url,omitempty"` // The URL of the image (may be trimmed). NodeID *dom.BackendNodeID `json:"nodeId,omitempty"` // No description. }
LargestContentfulPaint See https://github.com/WICG/LargestContentfulPaint and largest_contentful_paint.idl
type LayoutShift ¶
type LayoutShift struct { Value float64 `json:"value"` // Score increment produced by this event. HadRecentInput bool `json:"hadRecentInput"` // No description. LastInputTime network.TimeSinceEpoch `json:"lastInputTime"` // No description. Sources []LayoutShiftAttribution `json:"sources"` // No description. }
LayoutShift See https://wicg.github.io/layout-instability/#sec-layout-shift and layout_shift.idl
type LayoutShiftAttribution ¶
type LayoutShiftAttribution struct { PreviousRect dom.Rect `json:"previousRect"` // No description. CurrentRect dom.Rect `json:"currentRect"` // No description. NodeID *dom.BackendNodeID `json:"nodeId,omitempty"` // No description. }
LayoutShiftAttribution
type TimelineEvent ¶
type TimelineEvent struct { FrameID page.FrameID `json:"frameId"` // Identifies the frame that this event is related to. Empty for non-frame targets. Type string `json:"type"` // The event type, as specified in https://w3c.github.io/performance-timeline/#dom-performanceentry-entrytype This determines which of the optional "details" fiedls is present. Name string `json:"name"` // Name may be empty depending on the type. Time network.TimeSinceEpoch `json:"time"` // Time in seconds since Epoch, monotonically increasing within document lifetime. Duration *float64 `json:"duration,omitempty"` // Event duration, if applicable. LcpDetails *LargestContentfulPaint `json:"lcpDetails,omitempty"` // No description. LayoutShiftDetails *LayoutShift `json:"layoutShiftDetails,omitempty"` // No description. }
TimelineEvent
type TimelineEventAddedClient ¶
type TimelineEventAddedClient interface { // Recv calls RecvMsg on rpcc.Stream, blocks until the event is // triggered, context canceled or connection closed. Recv() (*TimelineEventAddedReply, error) rpcc.Stream }
TimelineEventAddedClient is a client for TimelineEventAdded events. Sent when a performance timeline event is added. See reportPerformanceTimeline method.
type TimelineEventAddedReply ¶
type TimelineEventAddedReply struct {
Event TimelineEvent `json:"event"` // No description.
}
TimelineEventAddedReply is the reply for TimelineEventAdded events.
