Struct Metrics 

pub struct Metrics {
    pub fps: f32,
    pub frame_ms_avg: f32,
    pub frame_ms_p99: f32,
    pub frames_total: u64,
    pub frames_dropped: u64,
    pub gpu_bytes: u64,
    pub draw_calls: u32,
}

A snapshot of the current diagnostics, mirroring the C ABI RlxMetrics struct (ADR-0008) on the native side so both frontends surface identical numbers from one computation.

Fields

fps: f32

Frames per second over the retained window.

frame_ms_avg: f32

Mean frame time over the window, in milliseconds.

frame_ms_p99: f32

99th-percentile frame time over the window, in milliseconds.

frames_total: u64

Frames recorded since creation (monotonic).

frames_dropped: u64

Frames the renderer skipped (surface acquire returned nothing).

gpu_bytes: u64

Core-tracked GPU resource bytes — an approximation (wgpu does not report driver device memory), dominated by the swapchain. A trend indicator.

draw_calls: u32

Draw/render-pass calls issued on the last frame.

Trait Implementations

impl Clone for Metrics

fn clone(&self) -> Metrics

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Metrics

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Metrics

fn default() -> Metrics

Returns the “default value” for a type.

impl PartialEq for Metrics

fn eq(&self, other: &Metrics) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Metrics

impl StructuralPartialEq for Metrics
