VkImageTiling

Possible values of VkImageCreateInfo::tiling, specifying the tiling arrangement of texel blocks in an image, are:

typedef enum VkImageTiling {
    VK_IMAGE_TILING_OPTIMAL = 0,
    VK_IMAGE_TILING_LINEAR = 1,
    // Provided by extensions
    VK_IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT = -999999000,
} VkImageTiling;

pub struct ImageTiling(u32);
impl ImageTiling {
    pub const OPTIMAL: Self = 0;
    pub const LINEAR: Self = 1;
    pub const DRM_FORMAT_MODIFIER_EXT: Self = -999999000;
}

• VK_IMAGE_TILING_OPTIMAL specifies optimal tiling (texels are laid out in an implementation-dependent arrangement, for more efficient memory access).
• VK_IMAGE_TILING_LINEAR specifies linear tiling (texels are laid out in memory in row-major order, possibly with some padding on each row).
• VK_IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT specifies that the image’s tiling is defined by a Linux DRM format modifier. The modifier is specified at image creation with VkImageDrmFormatModifierListCreateInfoEXT or VkImageDrmFormatModifierExplicitCreateInfoEXT, and can be queried with vkGetImageDrmFormatModifierPropertiesEXT.
