}

Stencil mask operation.

Variants

Keep

Keep the current value in the stencil buffer (no change).

Zero

Set the value in the stencil buffer to zero.

Replace

Set the stencil buffer value to value from StencilSide

IncrementClamp

Increment the stencil buffer value, clamping to its maximum value.

IncrementWrap

Increment the stencil buffer value, wrapping around to 0 on overflow.

DecrementClamp

Decrement the stencil buffer value, clamping to its minimum value.

DecrementWrap

Decrement the stencil buffer value, wrapping around to the maximum value on overflow.

Invert

Bitwise invert the current value in the stencil buffer.

Trait Implementations

impl PartialOrd<StencilOp> for StencilOp

fn partial_cmp(&self, other: &StencilOp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Hash for StencilOp

fn hash<__H>(&self, state: &mut __H) where     __H: Hasher,

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,

Feeds a slice of this type into the given [Hasher].

impl Clone for StencilOp

fn clone(&self) -> StencilOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StencilOp

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

Formats the value using the given formatter.

impl Copy for StencilOp

impl Ord for StencilOp

fn cmp(&self, other: &StencilOp) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl Eq for StencilOp

impl PartialEq<StencilOp> for StencilOp

fn eq(&self, other: &StencilOp) -> bool
