Struct ShadowBatchSetKey

pub struct ShadowBatchSetKey {
    pub pipeline: CachedRenderPipelineId,
    pub draw_function: DrawFunctionId,
    pub material_bind_group_index: Option<u32>,
    pub vertex_slab: SlabId,
    pub index_slab: Option<SlabId>,
}

Information that must be identical in order to place opaque meshes in the same batch set.

A batch set is a set of batches that can be multi-drawn together, if multi-draw is in use.

Fields

pipeline: CachedRenderPipelineId

The identifier of the render pipeline.

draw_function: DrawFunctionId

The function used to draw.

material_bind_group_index: Option<u32>

The ID of a bind group specific to the material.

In the case of PBR, this is the MaterialBindGroupIndex.

vertex_slab: SlabId

The ID of the slab of GPU memory that contains vertex data.

For non-mesh items, you can fill this with 0 if your items can be multi-drawn, or with a unique value if they can’t.

index_slab: Option<SlabId>

The ID of the slab of GPU memory that contains index data, if present.

For non-mesh items, you can safely fill this with None.

Trait Implementations

impl Clone for ShadowBatchSetKey

fn clone(&self) -> ShadowBatchSetKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for ShadowBatchSetKey

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 Ord for ShadowBatchSetKey

fn cmp(&self, other: &ShadowBatchSetKey) -> 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 ShadowBatchSetKey

fn eq(&self, other: &ShadowBatchSetKey) -> 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 ShadowBatchSetKey

fn partial_cmp(&self, other: &ShadowBatchSetKey) -> 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.

impl PhaseItemBatchSetKey for ShadowBatchSetKey

fn indexed(&self) -> bool

Returns true if this batch set key describes indexed meshes or false if it describes non-indexed meshes.
