    pub usage: TextureUsages,
    pub format: TextureFormat,
    pub width: u32,

§usage: TextureUsages

The usage of the swap chain. The only supported usage is RENDER_ATTACHMENT.

§format: TextureFormat

The texture format of the swap chain. The only formats that are guaranteed are Bgra8Unorm and Bgra8UnormSrgb

§width: u32

Width of the swap chain. Must be the same size as the surface.

§height: u32

Height of the swap chain. Must be the same size as the surface.

§present_mode: PresentMode

Presentation mode of the swap chain. Fifo is the only mode guaranteed to be supported. FifoRelaxed, Immediate, and Mailbox will crash if unsupported, while AutoVsync and AutoNoVsync will gracefully do a designed sets of fallbacks if their primary modes are unsupported.

§alpha_mode: CompositeAlphaMode

Specifies how the alpha channel of the textures should be handled during compositing.

§view_formats: Vec<TextureFormat, Global>

Specifies what view formats will be allowed when calling create_view() on texture returned by get_current_texture().

View formats of the same format as the texture are always allowed.

Note: currently, only the srgb-ness is allowed to change. (ex: Rgba8Unorm texture + Rgba8UnormSrgb view)
