Constants passed to WebGLRenderingContext.stencilFunc().

Variants

Never

Passed to depthFunction or stencilFunction to specify depth or stencil tests will never pass. i.e. Nothing will be drawn.

Always

Passed to depthFunction or stencilFunction to specify depth or stencil tests will always pass. i.e. Pixels will be drawn in the order they are drawn.

Less

Passed to depthFunction or stencilFunction to specify depth or stencil tests will pass if the new depth value is less than the stored value.

Equal

Passed to depthFunction or stencilFunction to specify depth or stencil tests will pass if the new depth value is equals to the stored value.

Lequal

Passed to depthFunction or stencilFunction to specify depth or stencil tests will pass if the new depth value is less than or equal to the stored value.

Greater

Passed to depthFunction or stencilFunction to specify depth or stencil tests will pass if the new depth value is greater than the stored value.

Gequal

Passed to depthFunction or stencilFunction to specify depth or stencil tests will pass if the new depth value is greater than or equal to the stored value.

Notequal

Passed to depthFunction or stencilFunction to specify depth or stencil tests will pass if the new depth value is not equal to the stored value.

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 FromWasmAbi for StencilTest

type Abi = u32

The wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for StencilTest

type Abi = u32

The wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for StencilTest

fn is_none(val: &u32) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for StencilTest

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl WasmDescribe for StencilTest

fn describe()

impl Copy for StencilTest
