Struct FrameTimings 

pub struct FrameTimings {
    pub event_processing: u32,
    pub runtime_messages: u32,
    pub build: u32,
    pub layout: u32,
    pub composite: u32,
    pub semantics: u32,
    pub paint: u32,
    pub cpu_total: u32,
}

Monotonic per-phase CPU durations for exactly one frame, in microseconds.

Phases do not nest: each duration covers only work attributed to that phase, so the sum equals the measured CPU frame cost.

Fields

event_processing: u32

Input dispatch before the frame began.

runtime_messages: u32

Tokio/UI message drain and async completions.

build: u32

BUILD phase: widget updates and reactive rebuilds.

layout: u32

LAYOUT phase.

composite: u32

COMPOSITE phase (retained layer transforms/opacity/effects).

semantics: u32

SEMANTICS phase.

paint: u32

PAINT phase including display-list flattening.

cpu_total: u32

Sum of all phases above.
