Enum RenderOperation 

pub enum RenderOperation {
    Stencil,
    Clip,
    UnClip,
    Color,
    SaveAlphaContext,
    ScaleAlphaContext,
    RestoreAlphaContext,
}

Which shader to use for rendering a shape

Variants

Stencil

Prepare rendering the Shape

Clip

Start using the rendered Shape as stencil for other Shapes

UnClip

Stop using the rendered Shape as stencil for other Shapes

Color

Render the Shape as a solid color using alpha blending

SaveAlphaContext

Start using the rendered Shape as opacity group for other Shapes

ScaleAlphaContext

Second step of RenderOperation::SaveAlphaContext, needs its own wgpu::RenderPass

RestoreAlphaContext

Stop using the rendered Shape as opacity group for other Shapes

Trait Implementations

impl Clone for RenderOperation

fn clone(&self) -> RenderOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RenderOperation

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

Formats the value using the given formatter.

impl Ord for RenderOperation

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RenderOperation

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RenderOperation

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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