Struct DrawRingProgress

pub struct DrawRingProgress {
    pub rect: Rect,
    pub thickness: f32,
    pub fraction: f32,
    pub track_color: Color,
    pub fill_color: Color,
    pub start_angle: f32,
}

Circular progress-ring primitive.

Numeric inputs are stored verbatim. The conventional fraction range is 0.0..=1.0, but this type does not clamp it or reject negative/non-finite thicknesses and angles.

Examples

use ailloli_ui_core::{Color, Rect};
use ailloli_ui_runtime::scene::DrawRingProgress;
let ring = DrawRingProgress {
    rect: Rect::new(0.0, 0.0, 24.0, 24.0), thickness: 2.0, fraction: 0.5,
    track_color: Color::BLACK, fill_color: Color::WHITE,
    start_angle: -std::f32::consts::FRAC_PI_2,
};
assert_eq!(ring.fraction, 0.5);

Fields

rect: Rect

Outer ring rectangle in window-space logical pixels.

thickness: f32

Requested stroke thickness in logical pixels.

fraction: f32

Requested filled revolution fraction; conventionally 0.0..=1.0.

track_color: Color

Linear-RGBA color of the complete background track.

fill_color: Color

Linear-RGBA color of the fractional foreground arc.

start_angle: f32

Radians, with -FRAC_PI_2 meaning top-center start.

Trait Implementations

impl Clone for DrawRingProgress

fn clone(&self) -> DrawRingProgress

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DrawRingProgress

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

Formats the value using the given formatter.

impl PartialEq for DrawRingProgress

fn eq(&self, other: &DrawRingProgress) -> 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.
