Struct SDL_GPUSwapchainComposition 

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

Specifies the texture format and colorspace of the swapchain textures.

SDR will always be supported. Other compositions may not be supported on certain systems.

It is recommended to query SDL_WindowSupportsGPUSwapchainComposition after claiming the window if you wish to change the swapchain composition from SDR.

• SDR: B8G8R8A8 or R8G8B8A8 swapchain. Pixel values are in sRGB encoding.
• SDR_LINEAR: B8G8R8A8_SRGB or R8G8B8A8_SRGB swapchain. Pixel values are stored in memory in sRGB encoding but accessed in shaders in “linear sRGB” encoding which is sRGB but with a linear transfer function.
• HDR_EXTENDED_LINEAR: R16G16B16A16_FLOAT swapchain. Pixel values are in extended linear sRGB encoding and permits values outside of the [0, 1] range.
• HDR10_ST2084: A2R10G10B10 or A2B10G10R10 swapchain. Pixel values are in BT.2020 ST2084 (PQ) encoding.

Available Since: This enum is available since SDL 3.2.0.

Trait Implementations

impl Clone for SDL_GPUSwapchainComposition

fn clone(&self) -> SDL_GPUSwapchainComposition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SDL_GPUSwapchainComposition

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

Formats the value using the given formatter.

impl Hash for SDL_GPUSwapchainComposition

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SDL_GPUSwapchainComposition

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