Enum naga::ConservativeDepth

pub enum ConservativeDepth {
    GreaterEqual,
    LessEqual,
    Unchanged,
}

Enables adjusting depth without disabling early Z.

SPIR-V: ExecutionMode DepthGreater/DepthLess/DepthUnchanged GLSL: layout (depth_<greater/less/unchanged/any>) out float gl_FragDepth;

• depth_any option behaves as if the layout qualifier was not present. HLSL: SV_Depth/SV_DepthGreaterEqual/SV_DepthLessEqual

Variants

GreaterEqual

Shader may rewrite depth only with a value greater than calculated;

LessEqual

Shader may rewrite depth smaller than one that would have been written without the modification.

Unchanged

Shader may not rewrite depth value.

impl Ord for ConservativeDepth

fn cmp(&self, other: &ConservativeDepth) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<ConservativeDepth> for ConservativeDepth

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<ConservativeDepth> for ConservativeDepth

fn partial_cmp(&self, other: &ConservativeDepth) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
