pub struct SparseStorage<T: Default> {
    pub cell_size: i32,
    pub cells: FnvHashMap<CellIdx, T>,
}
Expand description

SparseStorage stores cells in a FastMap to be used in a Grid. It is Sparse because cells are eagerly allocated, and cleaned when they are empty. It implements the Storage trait.
