Implementations

impl Renderer

pub async fn new() -> Result<Self>

pub fn create_texture(&self, width: u32, height: u32) -> (Texture, BindGroup)

Creates a reusable RGBA8 texture with a matching bind group. Live wallpapers upload new frame data into it via update_texture.

pub fn update_texture( &self, texture: &Texture, rgba: &[u8], width: u32, height: u32, )

Replaces the contents of a texture created by create_texture.

pub fn load_texture(&self, image: &DynamicImage) -> Result<(Texture, BindGroup)>

pub fn update_uniforms(&self, uniforms: Uniforms)

pub fn render_frame(&self, request: FrameRequest<'_>) -> Result<FrameStatus>

Renders the given texture bind groups to a wgpu Surface for one frame. bg_bind = old wallpaper, new_bind = new wallpaper, transitioned by effect.
