Fields

compare: CompareOp

Comparison operation between value stored in stencil buffer and refence value.

compare_mask: State<u32>

Selects the bits of the unsigned integer stencil values participating in the stencil test.

write_mask: State<u32>

Selects the bits of the unsigned integer stencil values updated by the stencil test in the stencil buffer.

reference: State<u32>

Reference value for comparison and operations.

fail: StencilOp

Action performed on samples that fail the stencil test.

pass: StencilOp

Action performed on samples that pass both the depth and stencil tests.

depth_fail: StencilOp

Action performed on samples that pass the stencil test and fail the depth test.

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

Formats the value using the given formatter.

impl Hash for StencilTest

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<StencilTest> for StencilTest

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