Enum vulkano::pipeline::graphics::depth_stencil::CompareOp

#[non_exhaustive]
#[repr(i32)]
pub enum CompareOp {
    Never = 0,
    Less = 1,
    Equal = 2,
    LessOrEqual = 3,
    Greater = 4,
    NotEqual = 5,
    GreaterOrEqual = 6,
    Always = 7,
}

Specifies how two values should be compared to decide whether a test passes or fails.

Used for both depth testing and stencil testing.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Never = 0

The test never passes.

Less = 1

The test passes if value < reference_value.

Equal = 2

The test passes if value == reference_value.

LessOrEqual = 3

The test passes if value <= reference_value.

Greater = 4

The test passes if value > reference_value.

NotEqual = 5

The test passes if value != reference_value.

GreaterOrEqual = 6

The test passes if value >= reference_value.

Always = 7

The test always passes.

Trait Implementations

impl Clone for CompareOp

fn clone(&self) -> CompareOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompareOp

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

Formats the value using the given formatter.

impl From<CompareOp> for CompareOp

fn from(val: CompareOp) -> Self

Converts to this type from the input type.

impl Hash for CompareOp

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 CompareOp

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

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

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

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

impl TryFrom<CompareOp> for CompareOp

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: CompareOp) -> Result<Self, Self::Error>

Performs the conversion.
