Struct SDL_GPUPresentMode 

#[repr(transparent)]
pub struct SDL_GPUPresentMode(pub c_uint);

Specifies the timing that will be used to present swapchain textures to the OS.

VSYNC mode will always be supported. IMMEDIATE and MAILBOX modes may not be supported on certain systems.

It is recommended to query SDL_WindowSupportsGPUPresentMode after claiming the window if you wish to change the present mode to IMMEDIATE or MAILBOX.

• VSYNC: Waits for vblank before presenting. No tearing is possible. If there is a pending image to present, the new image is enqueued for presentation. Disallows tearing at the cost of visual latency.
• IMMEDIATE: Immediately presents. Lowest latency option, but tearing may occur.
• MAILBOX: Waits for vblank before presenting. No tearing is possible. If there is a pending image to present, the pending image is replaced by the new image. Similar to VSYNC, but with reduced visual latency.

Available Since: This enum is available since SDL 3.2.0.

Trait Implementations

impl Clone for SDL_GPUPresentMode

fn clone(&self) -> SDL_GPUPresentMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SDL_GPUPresentMode

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

Formats the value using the given formatter.

impl Hash for SDL_GPUPresentMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for SDL_GPUPresentMode

fn eq(&self, other: &SDL_GPUPresentMode) -> 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.
