Module URI constructor explain

require "uri"

u = URI.parse("https://www.google.com")  #<URI::HTTPS https://www.google.com>
v = URI("https://www.google.com")        #<URI::HTTPS https://www.google.com>
u == v                                   # => true

The URI.parse is easy to understand, it calls module_function parse on Module URI.

How to understand URI() in Ruby's context? What method does it called? Or is this a syntactic sugar?

Best answer on your question is source code. Code below executes when you call URI('http..') 

def URI(uri)
  if uri.is_a?(URI::Generic)
    uri
  elsif uri = String.try_convert(uri)
    URI.parse(uri)
  else
    raise ArgumentError,
      "bad argument (expected URI object or URI string)"
  end
end

As you can see under the hood this method allows you to pass any argument and be sure that program will throw ArgumentError if argument wasn't uri or instance of uri. So, in my opinion good practice to use URI('...') than URI.parse('...') with additional checks.
