Enum 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.

Platform specific

• Wayland: when the window is hidden and SwapInterval::Wait is used GlSurface::swap_buffers and any functions based on it may block until the window is visible again. Using this variant is not recommended on Wayland and instead the throttling should be performed by frame callbacks.

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 for SwapInterval

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

Tests for self and other values to be equal, and is used by ==.

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

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