Enum ConservativeRasterizationTier 

#[repr(i32)]
pub enum ConservativeRasterizationTier {
    NotSupported = 0,
    Tier1 = 1,
    Tier2 = 2,
    Tier3 = 3,
}

Identifies the tier level of conservative rasterization.

For more information: D3D12_CONSERVATIVE_RASTERIZATION_TIER enumeration

Variants

NotSupported = 0

Conservative rasterization is not supported.

Tier1 = 1

Tier 1 enforces a maximum 1/2 pixel uncertainty region and does not support post-snap degenerates. This is good for tiled rendering, a texture atlas, light map generation and sub-pixel shadow maps.

Tier2 = 2

Tier 2 reduces the maximum uncertainty region to 1/256 and requires post-snap degenerates not be culled. This tier is helpful for CPU-based algorithm acceleration (such as voxelization).

Tier3 = 3

Tier 3 maintains a maximum 1/256 uncertainty region and adds support for inner input coverage. Inner input coverage adds the new value SV_InnerCoverage to High Level Shading Language (HLSL). This is a 32-bit scalar integer that can be specified on input to a pixel shader, and represents the underestimated conservative rasterization information (that is, whether a pixel is guaranteed-to-be-fully covered). This tier is helpful for occlusion culling.

Implementations

impl ConservativeRasterizationTier

pub const fn from_repr( discriminant: i32, ) -> Option<ConservativeRasterizationTier>

Try to create Self from the raw representation

Trait Implementations

impl Clone for ConservativeRasterizationTier

fn clone(&self) -> ConservativeRasterizationTier

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConservativeRasterizationTier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ConservativeRasterizationTier

fn default() -> ConservativeRasterizationTier

Returns the “default value” for a type.

impl From<D3D12_CONSERVATIVE_RASTERIZATION_TIER> for ConservativeRasterizationTier

fn from(value: D3D12_CONSERVATIVE_RASTERIZATION_TIER) -> Self

Converts to this type from the input type.

impl Hash for ConservativeRasterizationTier

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ConservativeRasterizationTier

fn eq(&self, other: &ConservativeRasterizationTier) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
