Struct SurfaceKey 

pub struct SurfaceKey {
    pub color_format: TextureFormat,
    pub depth_stencil_format: Option<TextureFormat>,
    pub sample_count: u32,
}

The render target a pipeline is specialized for.

Width and height are excluded: a pipeline does not depend on the size of the target it draws into.

Fields

color_format: TextureFormat

The format of the color attachment.

depth_stencil_format: Option<TextureFormat>

The format of the depth-stencil attachment, if the pass has one.

sample_count: u32

The sample count the pass renders with.

Implementations

impl SurfaceKey

pub fn from_attachments(attachments: &RenderAttachments) -> Self

The surface a set of attachments describes.

The color format and sample count are read from the same attachment path, so they stay consistent: the MSAA view when one is set, the color view otherwise. A depth-only attachment set has no color view, so its key reports Rgba8UnormSrgb as the color format; a depth-only pipeline is the caller’s to build.
