from rust-sliding_windows.
using this would give users cheap immutable references to the original data and clones if they use multiple windows.
maybe a custom Cow like smartpointer or a wrapper is needed. One which can be turned into a Clone as soon as two of them exist simultaneously
from rust-sliding_windows.
the window smartpointer needs either a negative send bound or some sort of synchronization
from rust-sliding_windows.
what should be done if mutation happens while another, overlapping window is still reachable?
from rust-sliding_windows.
it's not possible to clone the older window as soon as another one gets spawned by next(), because window derefs to (maybe multiple) references, which cannot be changed.
Instead one could create another storage vec and store the new and following windows there. But that's a performance nightmare..
from rust-sliding_windows.
Derefs are gone with v3.0, maybe it's possible now
