Enum gfx_hal::pso::StencilOp

#[repr(u8)]
pub enum StencilOp {
    Keep,
    Zero,
    Replace,
    IncrementClamp,
    DecrementClamp,
    Invert,
    IncrementWrap,

}

The operation to use for stencil masking.

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 reference from StencilFace.

IncrementClamp

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

DecrementClamp

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

Invert

Bitwise invert the current value in the stencil buffer.

IncrementWrap

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

DecrementWrap

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

impl PartialEq<StencilOp> for StencilOp

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

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.

#[must_use] fn lt(&self, other: &Rhs) -> bool

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

#[must_use] fn le(&self, other: &Rhs) -> bool

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

#[must_use] fn gt(&self, other: &Rhs) -> bool

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

#[must_use] 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 Debug for StencilOp

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