◆ donner::editor::FrameCostBreakdown::Overlay
| struct donner::editor::FrameCostBreakdown::Overlay |
Cost counters for capturing and presenting selection/source-hover chrome.

|---|
|
int |
aabbCount = 0 |

|
Vector2i |
canvasSize = Vector2i::Zero() |
Viewport overlay size that would have been rasterized before immediate presentation. |
|
double |
captureMs = 0.0 |
Milliseconds spent capturing live DOM selection chrome into a snapshot. |
|
double |
drawMs = 0.0 |
Milliseconds spent drawing the captured chrome snapshot into a retained overlay payload. Zero for the editor's immediate screen-space overlay path. |
|
int |
handleCount = 0 |
Selection transform handles captured. |
|
bool |
hasLiveDragPreview = false |
True when a live drag preview was available while capturing the overlay. |
|
bool |
hasMarquee = false |
True when the overlay snapshot included a marquee rectangle. |
|
bool |
hasRepresentedDragPreview = false |
True when overlay chrome was projected to a represented drag preview for presentation. |
|
int |
hoverAabbCount = 0 |
Source-hover axis-aligned bounding boxes captured. |
|
int |
hoverPathCount = 0 |
Source-hover path items captured from geometry leaves. |
|
Vector2d |
liveDragTranslationDoc = Vector2d::Zero() |
Live document-space drag translation at overlay capture time. |
|
int |
pathCount = 0 |
Selection path items captured from geometry leaves. |
|
uint64_t |
payloadBytes = 0 |
Approximate retained overlay payload bytes. Zero for immediate screen-space presentation. |
|
Vector2d |
representedDragTranslationDoc = Vector2d::Zero() |
Document-space drag translation represented by the overlay presented this frame. |
|
int |
selectedElementCount = 0 |
Document elements selected when the overlay snapshot was captured. |
|
bool |
selectionBoundsOnly = false |
True when selected chrome used the large-selection combined-bounds LOD path. |
|
double |
snapshotMs = 0.0 |
Milliseconds spent ending the renderer frame and acquiring a retained overlay payload. Zero for the editor's immediate screen-space overlay path. |
|
int |
sourceHoverElementCount = 0 |
Source-hover elements included in the overlay snapshot. |
|
double |
uploadMs = 0.0 |
Milliseconds spent handing a retained overlay payload to the presentation texture cache. Zero for the editor's immediate screen-space overlay path. |
