Specificies which operation the GPU will do depending on the result of the stencil test.

Variants

Keep = 7_680

Keeps the value currently in the stencil buffer.

Zero = 0

Writes zero in the stencil buffer.

Replace = 7_681

Writes the reference value (stencil_reference_value_clockwise or stencil_reference_value_counter_clockwise) in the stencil buffer.

Increment = 7_682

Increments the value currently in the stencil buffer. If the value is the maximum, don’t do anything.

IncrementWrap = 34_055

Increments the value currently in the stencil buffer. If the value is the maximum, wrap to 0.

Decrement = 7_683

Decrements the value currently in the stencil buffer. If the value is 0, don’t do anything.

DecrementWrap = 34_056

Decrements the value currently in the stencil buffer. If the value is 0, wrap to -1.

Invert = 5_386

Inverts each bit of the value.

Trait Implementations

impl Clone for StencilOperation

fn clone(&self) -> StencilOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StencilOperation

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

Formats the value using the given formatter.

impl PartialEq for StencilOperation

fn eq(&self, other: &StencilOperation) -> 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.
