Struct FrameTimes 

#[non_exhaustive]
pub struct FrameTimes {
    pub update_us: u32,
    pub draw_us: u32,
    pub paint_us: u32,
    pub present_us: u32,
    pub frame_us: u32,
}

How long the parts of one frame took, in whole microseconds. Build it with FrameTimes::new (ADR-0039); a backend may add a part.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

update_us: u32

Game::frame from its start to the drawing: the input, the modules’ before_update and the screens’ update.

draw_us: u32

The drawing: the screens and the modules drawing the frame (Game::redraw).

paint_us: u32

The platform’s present: in shuyi-app, painting the frame into the window.

present_us: u32

From the end of the last frame to the start of this one, outside App: the backend’s buffer swap and its wait for vsync or the frame cap. 0 on the first frame measured.

frame_us: u32

present_us plus this frame from its start to its end: never less than the four above together. The rest is App’s own (the system’s events, the audio, the record).

Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FrameTimes

fn default() -> FrameTimes

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FrameTimes
