Struct SoftRenderer 

pub struct SoftRenderer { /* private fields */ }

CPU-based software renderer using a raw pixel framebuffer.

In the full implementation this would wrap a softbuffer::Surface. For M1 it is a pure-Rust pixel-buffer helper that does not require a display at build time.

Implementations

impl SoftRenderer

pub fn new() -> Self

Construct a new SoftRenderer.

pub fn clear_frame( &self, width: u32, height: u32, color: Color, ) -> Result<Vec<u32>, UiError>

Fill a framebuffer with a solid colour.

Returns a Vec<u32> of length width * height in 0xAARRGGBB format, every pixel set to color.

Errors

Currently infallible; returns Err only if a future implementation encounters a resource constraint.

pub fn render<F>( &self, width: u32, height: u32, background: Color, draw_fn: F, ) -> Framebuffer

where F: FnOnce(&mut Canvas<'_>),

Render a scene into a fresh Framebuffer of the given size.

The framebuffer is pre-filled with background; draw_fn receives a clipped Canvas to paint the scene. Returns the finished framebuffer.

impl SoftRenderer

pub fn with_size(_width: u32, _height: u32) -> Self

Pre-allocate the framebuffer for the given pixel dimensions.

Equivalent to SoftRenderer::new() — the renderer itself is stateless; the framebuffer is created on demand inside SoftRenderer::render. Provided for API parity with SoftBackend::with_quality.

Trait Implementations

impl Default for SoftRenderer

fn default() -> Self

Returns the “default value” for a type.
