How to declare 8-bit unsigned integer in ruby?

In c++ you can do:

uint8 foo_bar

How would we do the same thing in ruby? Any alternatives?

This post seems close to it maybe someone can explain?

Ruby abstracts away the internal storage of integers, so you don't have to worry about it.

If you assign an integer to a variable, Ruby will deal with the internals, allocating memory when needed. Smaller integers are of type Fixnum (stored in a single word), larger integers are of type Bignum.

a = 64
a.class  #=> Fixnum; stored in a single word
a += 1234567890
a.class  #=> Bignum; stored in more than a single word

Ruby is dynamically typed, so you cannot force a variable to contain only unsigned 8-bit integers (just as you cannot force a variable to only contain string values, etc.).

You don't declare types in Ruby. The language is dynamically typed.
