Struct FrameTiming 

pub struct FrameTiming {
    pub layout_time_ns: u64,
    pub paint_time_ns: u64,
    pub gpu_wait_time_ns: u64,
    pub total_time_ns: u64,
}

Frame timing data for a single frame.

All times are in nanoseconds for consistent units.

Example

use martensite_devtools::hud::FrameTiming;

let timing = FrameTiming {
    layout_time_ns: 500_000,
    paint_time_ns: 300_000,
    gpu_wait_time_ns: 100_000,
    total_time_ns: 900_000,
};
assert_eq!(timing.total_time_ns, 900_000);

Fields

layout_time_ns: u64

Time spent in layout passes (nanoseconds).

paint_time_ns: u64

Time spent encoding the paint list (nanoseconds).

gpu_wait_time_ns: u64

Time spent waiting for the GPU (nanoseconds).

total_time_ns: u64

Total frame time (nanoseconds).

Implementations

impl FrameTiming

pub fn from_ms(layout: f64, paint: f64, gpu_wait: f64, total: f64) -> Self

Creates a FrameTiming from millisecond values.

Example

use martensite_devtools::hud::FrameTiming;

let t = FrameTiming::from_ms(0.5, 0.3, 0.1, 0.9);
assert_eq!(t.layout_time_ns, 500_000);

pub fn add(&self, other: &Self) -> Self

Adds two FrameTiming values component-wise.

pub fn div(&self, n: u64) -> Self

Divides all components by a scalar.
