Struct vulkano::image::view::ComponentMapping[−][src]

pub struct ComponentMapping {
    pub r: ComponentSwizzle,
    pub g: ComponentSwizzle,
    pub b: ComponentSwizzle,
    pub a: ComponentSwizzle,
}

Specifies how the components of an image must be mapped.

When creating an image view, it is possible to ask the implementation to modify the value returned when accessing a given component from within a shader.

Fields

r: ComponentSwizzle

First component.

g: ComponentSwizzle

Second component.

b: ComponentSwizzle

Third component.

a: ComponentSwizzle

Fourth component.

Implementations

impl ComponentMapping[src]

pub fn is_identity(&self) -> bool[src]

Returns true if the component mapping is identity swizzled, meaning that all the members are Identity.

Certain operations require views that are identity swizzled, and will return an error otherwise. For example, attaching a view to a framebuffer is only possible if the view is identity swizzled.
