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.
