Struct FrameStats 

pub struct FrameStats {
    pub flush: Duration,
    pub layout: Duration,
    pub paint: Duration,
    pub list: Duration,
    pub damage: Duration,
    pub layout_ran: bool,
    pub nodes_painted: u32,
    pub damage_rects: u32,
    pub damage_pixels: u64,
    pub damage_pixels_before_merge: u64,
    pub flush_rounds: u32,
}

How long each step of the last frame took and how much work it did.

Fields

flush: Duration

Time spent running reactive effects and applying their updates.

layout: Duration

Time spent in the layout pass.

paint: Duration

Time spent in the paint pass.

list: Duration

Time spent rebuilding the display list.

damage: Duration

Time spent converting and merging the damage.

layout_ran: bool

Whether the layout pass ran the layout engine.

nodes_painted: u32

How many nodes the paint pass regenerated.

damage_rects: u32

How many physical rectangles the damage holds.

damage_pixels: u64

How many physical pixels the damage covers, counting an overlap once per rectangle.

damage_pixels_before_merge: u64

How many physical pixels the damage covered before the merge step collapsed the rectangles, counting an overlap once per rectangle.

Together with FrameStats::damage_pixels this shows what the merge step traded: rectangles for area.

flush_rounds: u32

How many flush and apply rounds the frame ran.
