Struct amethyst_rendy::batch::OrderedTwoLevelBatch

pub struct OrderedTwoLevelBatch<PK, SK, D> where
    PK: PartialEq,
    SK: PartialEq,  { /* fields omitted */ }

Batching implementation which provides two levels of indirection and grouping for a given batch. This batch method is used, for example, batching meshes and textures; for any given draw call, a user would want to batch all draws using a specific texture together, and then also group all draw calls for a specific mesh together.

PK - First level of batch grouping SK - Secondary level of batch grouping D - the actual final type being batched.

Internally, this batch type is implemented with sorted tuple Vec structures.

OrderedTwoLevelBatch differs from [TwoLevelBatch] in that it sorts and orders on both levels of batching.

Methods

impl<PK, SK, D> OrderedTwoLevelBatch<PK, SK, D> where
    PK: PartialEq,
    SK: PartialEq, 

pub fn swap_clear(&mut self)

Clears all data and indices from this batch set.

pub fn insert(&mut self, pk: PK, sk: SK, data: impl IntoIterator<Item = D>)

Inserts a set of batch data to the specified grouping.

pub fn data(&self) -> &Vec<D>

Returns the raw storage data of this batch container.

pub fn iter<'a>(&'a self) -> impl Iterator<Item = (&'a PK, &[(SK, Range<u32>)])>

Iterator that returns primary keys and all inner submitted batches

pub fn changed(&self) -> bool

Returns true if sorting this batch resulted in a change in order.

pub fn count(&self) -> usize

Returns the number of items currently in this batch.
