8593 :: Best way to turn byte array into int?

• xioren (orginal) [2021-11-05T15:00:50+01:00] view original

  Playing around with the new urandom proc from sysrand and am wondering how best to go about turning the returned byte array int a single int. I have a couple ideas but none seem like "the right way".

  Here's what I use. I expanded my types so you can see the raw array.

  func read(this:var array[SIZE, byte], T:typedesc, pos:Natural = 0):ptr T =
    result = cast[ptr T](addr this[pos])
  Run

  What about:

  import std/sysrand
  proc urand[T]():T =
    assert urandom(cast[var array[sizeof(T),byte]](result.addr)
  Run

  for value types only

  Think this will work for me, thanks.
