Enum sierra::StencilOp

pub enum StencilOp {
    Keep,
    Zero,
    Replace,
    IncrementAndClamp,
    DecrementAndClamp,
    Invert,
    IncrementAndWrap,
    DecrementAndWrap,
}

Defines what operation should be peformed on value in stencil buffer.

Variants

Keep

Keep the current value.

Zero

Write 0.

Replace

Replace value with reference value.

IncrementAndClamp

Increment value and clamp it to maximum value representable in stencil buffer format.

DecrementAndClamp

Decrement value and clamp to 0.

Invert

Invert all bits.

IncrementAndWrap

Increment value and wrap to 0 if maximum value representable in stencil buffer format would be exeeded.

DecrementAndWrap

Decrement value and wraps to maximum value representable in stencil buffer format if value would go below 0.

Trait Implementations

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

Formats the value using the given formatter.

impl Hash for StencilOp

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<StencilOp> for StencilOp

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