Struct GpuScene 

pub struct GpuScene { /* private fields */ }

A retained list of GPU-friendly drawing commands in a logical coordinate space. Build or update it with application state, then pass it to GpuView. Commands paint in insertion order.

Implementations

impl GpuScene

pub fn new(width: f32, height: f32) -> Self

pub fn size(&self) -> (f32, f32)

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn rect(self, bounds: GpuRect, color: Hsla) -> Self

Append a filled rectangle.

pub fn rounded_rect(self, bounds: GpuRect, color: Hsla, radius: f32) -> Self

Append a filled rounded rectangle.

pub fn bordered_rect( self, bounds: GpuRect, fill: Hsla, border: Hsla, border_width: f32, radius: f32, ) -> Self

Append a filled rectangle with a solid border.

pub fn push_rect(&mut self, bounds: GpuRect, color: Hsla)

pub fn texture(self, texture: GpuTexture, bounds: GpuRect) -> Self

Append a texture mapped over the supplied scene rectangle.

pub fn sprite( self, texture: GpuTexture, source: GpuRect, bounds: GpuRect, ) -> Self

Draw one normalized region of a texture into a scene rectangle.

source uses 0.0..=1.0 texture coordinates. This keeps sprite-sheet animation app-owned: select a frame while rebuilding the scene, without creating a new texture or decoding the atlas again.

pub fn background(self, texture: GpuTexture) -> Self

Append a texture covering the scene’s full logical bounds.

pub fn push_texture(&mut self, texture: GpuTexture, bounds: GpuRect)

pub fn push_sprite( &mut self, texture: GpuTexture, source: GpuRect, bounds: GpuRect, )

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuScene

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

Formats the value using the given formatter.
