Enum FramePacingMode 

pub enum FramePacingMode {
    Vsync,
    Hard60,
    Hard120,
    NoVsync,
}

How the shell paces its frames against the display.

Variants

Vsync

Pace frames to the display refresh interval. The production default: animations advance once per vsync instead of re-rendering uncapped.

Hard60

Cap frames at 60 per second with a timer, whatever the display refresh rate is.

Hard120

Cap frames at 120 per second with a timer, whatever the display refresh rate is.

NoVsync

Render as fast as possible. For perf harnesses and robot drivers that measure work throughput; saturates the GPU if used in a real app.

Implementations

impl FramePacingMode

pub const ALL: [Self; 4]

Every pacing mode, in the order the dev overlay lists them.

pub fn label(self) -> &'static str

Returns the short name the dev overlay shows for this mode.

pub fn target_fps(self) -> Option<u32>

Returns the frames per second this mode caps at with a timer, or None when the mode sets no cap.
