@thestinger r?
The 2_unlimited
functions are markedunsafe
since they may not terminate.The
state
fields of theUnfoldr
andScan
iterators are public, since being able to access the final state after the iteration has finished seems reasonable/possibly useful.Lastly, I converted the tests to use.to_vec
, which halves the amount of code for them, but it means that a.transform(|x| *x)
call is required on each iterator.(removed the 2 commits with
to_vec
andfoldl
.)
