Struct makepad_widgets::shader::std::os::cx_stdin::Swapchain

pub struct Swapchain<I> {
    pub width: u32,
    pub height: u32,
    pub presentable_images: [PresentableImage<I>; 2],
}

“Swapchains” group together some number (i.e. SWAPCHAIN_IMAGE_COUNT here) of “presentable images”, to form a queue of render targets which can be “presented” (to a surface, like a display, window, etc.) independently of rendering being done onto other “presentable images” in the “swapchain”.

Certain configurations of swapchains often have older/more specific names, e.g. “double buffering” for SWAPCHAIN_IMAGE_COUNT == 2 (or “triple” etc.).

Fields

width: u32

height: u32

presentable_images: [PresentableImage<I>; 2]

Trait Implementations

impl<I> Clone for Swapchain<I>where I: Clone,

fn clone(&self) -> Swapchain<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> DeBin for Swapchain<I>where I: DeBin,

fn de_bin(o: &mut usize, d: &[u8]) -> Result<Swapchain<I>, DeBinErr>

fn deserialize_bin(d: &[u8]) -> Result<Self, DeBinErr>

impl<I> DeJson for Swapchain<I>where I: DeJson,

fn de_json( s: &mut DeJsonState, i: &mut Chars<'_> ) -> Result<Swapchain<I>, DeJsonErr>

fn deserialize_json(input: &str) -> Result<Self, DeJsonErr>

impl<I> Debug for Swapchain<I>where I: Debug,

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

Formats the value using the given formatter.

impl<I> PartialEq<Swapchain<I>> for Swapchain<I>where I: PartialEq<I>,

fn eq(&self, other: &Swapchain<I>) -> 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.

impl<I> SerBin for Swapchain<I>where I: SerBin,

fn ser_bin(&self, s: &mut Vec<u8, Global>)

fn serialize_bin(&self) -> Vec<u8, Global>

impl<I> SerJson for Swapchain<I>where I: SerJson,

fn ser_json(&self, d: usize, s: &mut SerJsonState)

fn serialize_json(&self) -> String

impl<I> Copy for Swapchain<I>where I: Copy,

impl<I> StructuralPartialEq for Swapchain<I>
