give struct version: `class series def initialize(series) = @series = series def slices(n) raise argumenterror if n > @series.length @series.chars.each_cons(n).map(&:join) end end` in ruby

In Ruby, you can define structs using the Struct class. Here's an example of how you can give versioning to the Series class using a struct:

main.rb
class Series
  Version = Struct.new(:major, :minor, :patch)
  # ...
end

# Usage:
version = Series::Version.new(1, 0, 0)
puts "Series version #{version.major}.#{version.minor}.#{version.patch}"
194 chars
9 lines

In the code above, we define a struct called Version inside the Series class. The Version struct has three attributes: major, minor, and patch, representing the version number. You can assign values to these attributes when creating a new instance of the struct.

This example demonstrates how to give a struct versioning. However, you have provided code that defines a Series class with a constructor (initialize) and a method (slices). If you have specific requirements or need help with that code, please provide more details so that I can assist you further.
