remainingLength property
      
      int?
      get
      remainingLength
      
    
    
Should return the remaining length of the input data. If no information about the input
length is available, null should be returned.
The length is used to constrain the preallocation while decoding. Returning a garbage
length can open the doors for a denial of service attack to your application.
Otherwise, returning null can decrease the performance of your application.
Implementation
int? get remainingLength;
