Struct EglOffscreenContext

pub struct EglOffscreenContext { /* private fields */ }

Runtime-free EGL target for code that wants a GPU crate::render::Canvas without going through ltk::run.

This owns an EGL display, GLES context, and tiny pbuffer surface. The ltk GLES canvas still renders into its own FBO; the pbuffer exists only to make a valid EGL context current for GL calls. Compositors that already own a GL context should normally create Canvas::new_gles(...) themselves and pass it to UiSurface::from_canvas instead.
