Sets the preset dictionary and returns string. This method is available just only after Zlib::Deflate.new or Zlib::ZStream#reset method was called. See zlib.h for details.
Can raise errors of Z_STREAM_ERROR if a parameter is invalid (such as NULL dictionary) or the stream state is inconsistent, Z_DATA_ERROR if the given dictionary doesn’t match the expected one (incorrect adler32 value)
Provide the inflate stream with a dictionary that may be required in the future. Multiple dictionaries may be provided. The inflate stream will automatically choose the correct user-provided dictionary based on the stream’s required dictionary.
Sets the preset dictionary and returns string. This method is available just only after a Zlib::NeedDict exception was raised. See zlib.h for details.

Returns serialized iseq binary format data as a String object. A corresponding iseq object is created by RubyVM::InstructionSequence.load_from_binary() method.
String extra_data will be saved with binary data. You can access this data with RubyVM::InstructionSequence.load_from_binary_extra_data(binary).
Note that the translated binary data is not portable. You can not move this binary data to another machine. You can not use the binary data which is created by another version/another architecture of Ruby.
Returns the number of the first source line where the instruction sequence was loaded from.
For example, using irb:
iseq = RubyVM::InstructionSequence.compile('num = 1 + 2') #=> <RubyVM::InstructionSequence:<compiled>@<compiled>> iseq.first_lineno #=> 1
Return trace points in the instruction sequence. Return an array of [line, event_symbol] pair.
Returns the build_args used to install the gem
Sets the rubygems_version to the current RubyGems version.
