Struct SoftwareBackend 

pub struct SoftwareBackend { /* private fields */ }

This struct contains statistics as well as possible interactions with the software renderer.

Example

 use egui_software_backend::{App, SoftwareBackend};

struct MyApp {

}

impl App for MyApp {
    fn update(&mut self, ctx: &egui::Context, backend: &mut SoftwareBackend) {
        backend.set_capture_frame_time(true);


       egui::CentralPanel::default().show(ctx, |ui| {
       ui.label(format!(
          "Frame Time {}ms",
           backend.last_frame_time().unwrap_or_default().as_millis()
        ));
    });
   }
}

Implementations

impl SoftwareBackend

pub fn is_capture_frame_time(&self) -> bool

Returns true if the frame time for the next frame is captured.

pub fn set_capture_frame_time(&mut self, capture: bool)

Enables or disables capturing the frame time. Note that once this is called, the value persists until this function is called again. Calling this with true will not affect the current frame, so once this is called with true, you will need to wait for 2 more frames until you get a value.

pub fn last_frame_time(&self) -> Option<Duration>

Returns the rendering duration of the last frame if this information is available. Returns none otherwise. Note that this information is only captured is set_capture_frame_time is called with true.
