Struct Gpu 

pub struct Gpu { /* private fields */ }

Available on crate feature toolkit only.

EGL/GL state bound to a wl_surface, created once the surface has its first size. Owns the egui_glow painter and the dma-buf texture cache.

Implementations

impl Gpu

pub fn new(conn: &Connection, surface: &WlSurface, pw: i32, ph: i32) -> Gpu

Build the EGL/GLES context for surface at physical size pw×ph. Panics on EGL setup failure (the host can’t render without it).

pub fn resize(&self, pw: i32, ph: i32)

Resize the EGL window to a new physical size (after a surface configure / scale change).

pub fn render( &mut self, egui_ctx: &Context, raw_input: RawInput, ppp: f32, size_px: (u32, u32), backdrop: [f32; 4], run_ui: impl FnMut(&mut Ui, &mut dyn DmabufImporter), )

Run one egui frame and present it. run_ui builds the UI; it is handed the dma-buf importer (this owns the GL context) so capture frames become drawable textures. backdrop is the GL clear colour (premultiplied gamma).
