Stats

Markdown crates/ui/src/stats.rs docs.rs

use ui::{
    floating::{self, Floating},
    stats::Stats,
};

// Two fields on the view that mounts it: the meter, and where it floats.
meter: Entity<Stats>,
meter_at: Floating,

// In render, inside a `relative()` container.
floating::panel("meter", &self.meter_at, home, self.meter.clone())

A window at rest reads 0. Anything above it while nothing is moving means something is asking for frames — one mounted spinner at 120Hz cost 36% of a core on the machine this library was built on.

Readings
FPS This view's own renders, which is the window's draw count. The meter's own two draws a second are included.
CPU The whole process, user plus system, as a percentage of one core — getrusage, so — on the web build.
GPU Time spent on this window's frames. — on a renderer that does not report it.
MEM Resident bytes, sampled at the tick rather than differenced across one.

API

// ui::stats

/// The box's width, for a host placing the meter by its trailing edge.
pub const WIDTH: f32;

impl Stats {
    /// One per window — two mounted meters each count the other's frames.
    pub fn new(cx: &mut Context<Self>) -> Self;
}

// ...

Placement is the caller's. A floating panel makes it draggable; a corner works just as well.
