Struct RingProgressVertex

#[repr(C)]
pub struct RingProgressVertex {
    pub pos: [f32; 2],
    pub uv: [f32; 2],
    pub track_color: [f32; 4],
    pub fill_color: [f32; 4],
    pub size_px: [f32; 2],
    pub thickness_px: f32,
    pub fraction: f32,
    pub start_angle: f32,
}

Circular progress SDF vertex (position, UV, colors, size, thickness, fraction, start angle).

Examples

use ailloli_ui_render_wgpu::vertices::RingProgressVertex;
let vertex = RingProgressVertex { pos: [0.0; 2], uv: [0.0; 2], track_color: [0.0; 4],
    fill_color: [1.0; 4], size_px: [24.0; 2], thickness_px: 2.0,
    fraction: 0.5, start_angle: 0.0 };
assert_eq!(vertex.fraction, 0.5);

Fields

pos: [f32; 2]

Position in normalized device coordinates.

uv: [f32; 2]

Unit-quad coordinate used for ring distance evaluation.

track_color: [f32; 4]

Linear RGBA track color.

fill_color: [f32; 4]

Linear RGBA filled-arc color.

size_px: [f32; 2]

Ring bounding-box size in physical pixels.

thickness_px: f32

Ring thickness in physical pixels.

fraction: f32

Filled proportion, normally clamped to [0, 1] by the builder.

start_angle: f32

Arc start angle in radians.

Implementations

impl RingProgressVertex

pub const ATTRS: [VertexAttribute; 8]
