Struct eframe::Frame

pub struct Frame { /* private fields */ }

Represents the surroundings of your app.

It provides methods to inspect the surroundings (are we on the web?), allocate textures, and change settings (e.g. window size).

Implementations

impl Frame

pub fn is_web(&self) -> bool

True if you are in a web environment.

Equivalent to cfg!(target_arch = "wasm32")

pub fn info(&self) -> IntegrationInfo

Information about the integration.

pub fn storage(&self) -> Option<&dyn Storage>

A place where you can store custom data in a way that persists when you restart the app.

pub fn storage_mut(&mut self) -> Option<&mut (dyn Storage + 'static)>

A place where you can store custom data in a way that persists when you restart the app.

pub fn gl(&self) -> Option<&Arc<Context>>

A reference to the underlying glow (OpenGL) context.

This can be used, for instance, to:

• Render things to offscreen buffers.
• Read the pixel buffer from the previous frame (glow::Context::read_pixels).
• Render things behind the egui windows.

Note that all egui painting is deferred to after the call to App::update (egui only collects [egui::Shape]s and then eframe paints them all in one go later on).

To get a glow context you need to compile with the glow feature flag, and run eframe using Renderer::Glow.

pub fn wgpu_render_state(&self) -> Option<&RenderState>

The underlying WGPU render state.

Only available when compiling with the wgpu feature and using Renderer::Wgpu.

Can be used to manage GPU resources for custom rendering with WGPU using [egui::PaintCallback]s.
