Enum SampleRegion 

pub enum SampleRegion {
    Global,
    PaddedLocal(PaddingRect),
    Absolute(PxRect),
}

Defines the sampling requirements for a rendering command that needs a barrier.

Variants

Global

The command needs to sample from the entire previously rendered scene. This will cause a full-screen texture copy.

PaddedLocal(PaddingRect)

The command needs to sample from a region relative to its own bounding box.

Absolute(PxRect)

The command needs to sample from a specific, absolute region of the screen.

Implementations

impl SampleRegion

pub const ZERO_PADDING_LOCAL: Self

A zero-padding local barrier requirement for commands that only sample within their bounds.

pub const fn uniform_padding_local(padding: Px) -> Self

Creates a PaddedLocal barrier requirement with uniform sampling padding on all sides.

Trait Implementations

impl Clone for SampleRegion

fn clone(&self) -> SampleRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SampleRegion

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

Formats the value using the given formatter.

impl PartialEq for SampleRegion

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