Struct amethyst_rendy::batch::OneLevelBatch

pub struct OneLevelBatch<PK, D> where
    PK: Eq + Hash,  { /* fields omitted */ }

A batching implementation with one level of indexing. Data type D batched by primary key PK. Items with the same PK are always grouped.

Methods

impl<PK, D> OneLevelBatch<PK, D> where
    PK: Eq + Hash, 

pub fn clear_inner(&mut self)

Clears all data and indices from this batch set.

pub fn prune(&mut self)

Removes any empty grouping indicies.

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

Inserts the provided set of batch data for PK

pub fn data(&self) -> impl Iterator<Item = &Vec<D>>

Returns an iterator over batched data lists.

pub fn iter(&self) -> impl Iterator<Item = (&PK, Range<u32>)>

Returns an iterator over batched values, providing batch PK and data list.

pub fn count(&self) -> usize

Returns the number of items currently in this batch.
