Enum tetra::graphics::StencilTest

pub enum StencilTest {

}

The test for whether a pixel is visible when using a stencil.

Variants

Never

The pixel is never visible.

LessThan

The pixel is visible if the reference value is less than the value in the stencil buffer.

LessThanOrEqualTo

The pixel is visible if the reference value is less than or equal to the value in the stencil buffer.

EqualTo

The pixel is visible if the reference value is equal to the value in the stencil buffer.

NotEqualTo

The pixel is visible if the reference value is not equal to the value in the stencil buffer.

GreaterThan

The pixel is visible if the reference value is greater than the value in the stencil buffer.

GreaterThanOrEqualTo

The pixel is visible if the reference value is greater than or equal to the value in the stencil buffer.

Always

The pixel is always visible.

Trait Implementations

impl Clone for StencilTest

fn clone(&self) -> StencilTest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StencilTest

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