Enum FoldRoute 

pub enum FoldRoute {
    Slide(Slide),
    Mapped,
    Lanes,
}

How a fold reads an array that a mapping lays over storage, as fold_route chooses.

Variants

Slide(Slide)

Sliding folds over the source, as Slide classifies the array as windows along the folded axes.

Mapped

Through the mapping, as along_mapped reads it.

Lanes

From the array’s items, which it gathers once and keeps, or reads in place where a fold of every item reads a block of storage.
