pub struct GpuRenderer { /* private fields */ }

GPU描画コンテキスト

Implementations

impl GpuRenderer

pub async fn new(window: Arc<Window>, font_path: Option<&str>) -> Result<Self>

新しいGPUレンダラーを作成

pub fn resize(&mut self, new_size: PhysicalSize<u32>)

ウィンドウサイズが変更された時の処理

pub fn cache_stats(&self) -> Vec<CacheStatsSnapshot>

Returns the hit/miss/eviction counters of the internal text caches (layout, glyph bearings, glyph atlas). Empty when text rendering is unavailable.

pub fn parse_draw_commands(&mut self, commands: &[DrawCommand])

描画命令を解析して頂点バッファやテキストキューに登録

pub fn render(&mut self) -> Result<()>

フレームを描画

TODO: [wgpu::CurrentSurfaceTexture] をよりよく処理する必要があります。 現在は、 Success 時以外の結果を無視し、Errorにまとめて返す挙動をします。

pub fn set_scale_factor(&mut self, scale_factor: f64)

Trait Implementations

impl DrawSink for GpuRenderer

Presents through a wgpu surface bound to an OS window.

This is the shell’s default DrawSink. Callers above the seam only ever see the trait, so the fact that presentation is tied to a window surface stays contained here.

fn upload(&mut self, commands: &[DrawCommand])

Records and uploads commands for the next frame.

fn present(&mut self) -> Result<(), DrawError>

Draws and presents whatever upload recorded.

fn resize(&mut self, size: (u32, u32))

Notifies the sink that its drawable changed size, in physical pixels.

fn set_scale_factor(&mut self, scale_factor: f64)

Notifies the sink that the display scale factor changed.
