In Itertools there's Itertools::next_tuple():
https://docs.rs/itertools/0.10.3/itertools/trait.Itertools.html#method.next_tuple
But for the Rust stdlib I prefer something more general, an array chunks for iterator (that perhaps works only on Copy types?):
Iterator::array_chunks_copy::()
It's similar to slice::array_chunks but I think it should return actual arrays instead of array references.
Beside this functions I'd like a rustc (or Clippy) lint that warns against returning large chunks.
