Struct SwapchainConfig

pub struct SwapchainConfig {
    pub present_mode: PresentMode,
    pub composite_alpha_mode: CompositeAlphaMode,
    pub format: Format,
    pub extent: Extent2D,
    pub image_count: u32,
    pub image_layers: u16,
    pub image_usage: Usage,
}

Contains all the data necessary to create a new Swapchain: color, depth, and number of images.

Examples

This type implements the builder pattern, method calls can be easily chained.

let config = SwapchainConfig::new(100, 100, Format::Bgra8Unorm, 2);

Fields

present_mode: PresentMode

Presentation mode.

composite_alpha_mode: CompositeAlphaMode

Alpha composition mode.

format: Format

Format of the backbuffer images.

extent: Extent2D

Requested image extent. Must be in SurfaceCapabilities::extents range.

image_count: u32

Number of images in the swapchain. Must be in SurfaceCapabilities::image_count range.

image_layers: u16

Number of image layers. Must be lower or equal to SurfaceCapabilities::max_image_layers.

image_usage: Usage

Image usage of the backbuffer images.

Implementations

impl SwapchainConfig

pub fn new( width: u32, height: u32, format: Format, image_count: u32, ) -> SwapchainConfig

Create a new default configuration (color images only).

Examples

pub fn from_caps( caps: &SurfaceCapabilities, format: Format, default_extent: Extent2D, ) -> SwapchainConfig

Create a swapchain configuration based on the capabilities returned from a physical device query. If the surface does not specify a current size, default_extent is clamped and used instead.

pub fn with_present_mode(self, mode: PresentMode) -> SwapchainConfig

Specify the presentation mode.

Examples

pub fn with_image_usage(self, usage: Usage) -> SwapchainConfig

Specify the usage of backbuffer images.

Examples
