Enum PresentInterval 

pub enum PresentInterval {
    VSync,
    MinLatencyPresent(usize),
}

The policy of using V-Sync for the smoothest present() or the minimum-latency tearing present().

Variants

VSync

Enable V-Sync for the smoothest present() with minimum power consumption.

• If your device supports adaptive presentation interval, it will be automatically enabled.

MinLatencyPresent(usize)

Disable V-Sync for maximum framerate with minimum-latency tearing present().

• The usize is the max concurrent frames; if the device doesn’t limit the max concurrent frames, you have to provide one.
• If you give zero, a default number of the max concurrent frames will be used.
• The greater the number you give, the higher the framerate you could achieve, but the more memory will be used to store the framebuffer.

Implementations

impl PresentInterval

pub fn is_vsync(&self) -> bool

Is V-Sync requested?

pub fn is_minimum_latency_present(&self) -> Option<usize>
