class YARP::LibRubyParser::YPString

so it doesn’t have to be an FFI::Struct.
This object represents a yp_string_t. We only use it as an opaque pointer,

def initialize(pointer) 

def initialize(pointer)
  @pointer = pointer
end

def length 

def length
  LibRubyParser.yp_string_length(pointer)
end

def read 

def read
  source.read_string(length)
end

def source 

def source
  LibRubyParser.yp_string_source(pointer)
end
