Assign the contents of the location at i in vec to value.
Swap the values of the locations in vec at i and j.
Assign the value of every location in vec between start and end to fill. start defaults to 0 and end defaults to the length of vec.
Destructively reverse the contents of vec between start and end. start defaults to 0 and end defaults to the length of vec.
Copy a block of elements from source to target, both of which must be vectors, starting in target at tstart and starting in source at sstart, ending when (send - sstart) elements have been copied. It is an error for target to have a length less than (tstart + send - sstart). sstart defaults to 0 and send defaults to the length of source.
Like vector-copy!
, but this copies the elements in the reverse
order. It is an error if target and source are identical
vectors and the target and source ranges overlap; however,
if tstart = sstart, vector-reverse-copy!
behaves as
(vector-reverse! target tstart send)
would.
