Enum glutin::surface::SwapInterval

pub enum SwapInterval {
    DontWait,
    Wait(NonZeroU32),
}

A swap interval.

The default swap interval for your Surface is platform-dependent. For example, on EGL it is 1 by default, but on GLX it is 0 by default.

Please note that your application’s desired swap interval may be overridden by external, driver-specific configuration, which means that you can’t know in advance whether crate::surface::GlSurface::swap_buffers will block or not.

Variants

DontWait

When this variant is used calling [crate::surface::GlSurface::swap_buffers] will not block.

Wait(NonZeroU32)

The swap is synchronized to the n’th video frame. This is typically set to 1 to enable vsync and prevent screen tearing.

Trait Implementations

impl Clone for SwapInterval

fn clone(&self) -> SwapInterval

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SwapInterval

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

Formats the value using the given formatter.

impl PartialEq<SwapInterval> for SwapInterval

fn eq(&self, other: &SwapInterval) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
