Struct bevy_render::batch::Batcher

pub struct Batcher<TKey, TValue, TData> where
    TKey: Key,  {
    pub batches: HashMap<BatchKey<TKey>, Batch<TKey, TValue, TData>>,
    pub is_index: Vec<fn(_: &TKey) -> bool>,
    pub key_states: HashMap<TValue, BatcherKeyState<TKey>>,
    pub key_count: usize,
}

An unordered batcher intended to support an arbitrary number of keys of the same type (but with some distinguishing factor) NOTE: this may or may not be useful for anything. when paired with a higher-level "BatcherSet" it would allow updating batches

Fields

batches: HashMap<BatchKey<TKey>, Batch<TKey, TValue, TData>>

is_index: Vec<fn(_: &TKey) -> bool>

key_states: HashMap<TValue, BatcherKeyState<TKey>>

key_count: usize
