marshalling - ruby Marshal serialization -

Thanks for your time!

I get a class like this

  class Vuser def start (logfile_name, iteration_hash) @logfile_name = logfile_name @iteration_hash = iteration_hash end attr_accessor: logfile_name ,: iteration_hash def Output_iteration_info () says @logfile_name @iteration_hash puts the end end   
 and there will be an array to store examples of vusor class. Assume that the name of the array is vuser_ary.  
 I want to store this array (vuser_ary) in a binary file and I think it is called serialization. I can get it martial in google and standard library. Here's an example of how I do this on the Internet according to this example:  
  #serialization File.open ("some.file", "wb"). File | Marshall Dump (vuser_ary, file) End # loading vuser_ary = Zero file. Open ("some.file", "rb") {| F | Vuser_ary = Marshal.load (f)}   
 But when I check something size File. I think it's just four bytes, so I know that some data stored in. The file can be referenced but the value of vuser_ary is not.  
 Then my question is how do I store the value of vuser_ary in a binary file. How do I change my code to get this? ! Thanks in advance  
 The stored value in Btw: vuser_ary will be as follows:  
 RO_3.2_S4_CommericalRealEstate1_274.log  
 {1 = & gt; "Unsuccessful" 2 = & gt; "Unsuccessful", 3 = & gt; "Pass", 4 = & gt; "Pass", 5 = & gt; "Unsuccessful"}  
 RO_3.2_S4_CommericalRealEstate1_275.log  
 {11 = & gt; "Failed", 2 = & gt; "Failed", 3 = & gt; "Failed", 4 = & gt; "Pass", 5 = & gt; "Unsuccessful"  
 RO_3 .2_S4_CommericalRealEstate1_276.log  
 {1 = & gt; "Unsuccessful", 2 = & gt; "Unsuccessful", 3 = & gt; "Pass", 4 = & gt; "Pass", 5 = & gt; "Fail"}  
 RO_3.2_S4_CommericalRealEstate1_277.log  
 {1 = "Fail", 2 => "Failed", 3 = & gt; "Pass" , 4 = & gt; "Failed", 5 = & gt; "Fail"}  
 RO_3.2_S4_CommericalRealEstate1_278.log  
 {1 = & gt; "Failed", 2 = & gt; "Unsuccessful", 3 = & gt; "Pass", 4 = & gt; "Pass", 5 = & gt; "Unsuccessful"}  
 RO_3.2_S4_CommericalRealEstate1_279.log  
 {1 = & gt; "Unsuccessful", 2 = & gt; "Unsuccessful", 3 = & gt; "Pass", 4 = & gt; "Pass", 5 = & gt; "Unsuccessful"}  
 RO_3.2_S4_CommericalRealEstate1_280.log  
 {1 = & gt; "Failed", 2 = & gt; "Failed", 3 = & gt; "Failed", 4 = & gt; "Pass", 5 = & gt; "Fail"}   
 
 
 Four bytes? It happens that martializing the empty table  []  produces a 4-byte string on my Ruby:  
  & gt; Marshall Stands ([]). Length = & gt; 4   
 Are you sure that  vuser_ary  is empty when you try to martial it?  
 This happens, for reference "objects and objects: there are no signs in Ruby, so if you have an array (and it is empty), then it will be martial:  
  & gt; Marshal Dump ([1, 2, 3]). Length => 10   
 For good measure:  
  & gt; Vuser_ary = [{1 = "Failed", 2 = & gt; "Failed", 3 = & gt; "Pass", 4 = & gt; "Pass", 5 = & gt; ; "Failed"}] = & gt; [1 = & gt; "failed", 2 = & gt; "failed", 3 = & gt; "pass", 4 = & gt; "pass", 5 = & Gt; "failed"}] & gt; Marshall Dump (vuser_ary). Length => 72
