Returns new ancillary data for IPV6_PKTINFO.
IPV6_PKTINFO is defined by RFC 3542.
addr = Addrinfo.ip("::1") ifindex = 0 p Socket::AncillaryData.ipv6_pktinfo(addr, ifindex) #=> #<Socket::AncillaryData: INET6 IPV6 PKTINFO ::1 ifindex:0>
Extracts addr and ifindex from IPV6_PKTINFO ancillary data.
IPV6_PKTINFO is defined by RFC 3542.
addr = Addrinfo.ip("::1") ifindex = 0 ancdata = Socket::AncillaryData.ipv6_pktinfo(addr, ifindex) p ancdata.ipv6_pktinfo #=> [#<Addrinfo: ::1>, 0]
Same as IO.

Iterates over keys and objects in a weakly referenced object
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 absolute path of this instruction sequence.
nil if the iseq was evaluated from a string.
For example, using ::compile_file:
# /tmp/method.rb
def hello
puts "hello, world"
end
# in irb
> iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.absolute_path #=> /tmp/method.rb
Returns the base label of this instruction sequence.
For example, using irb:
iseq = RubyVM::InstructionSequence.compile('num = 1 + 2') #=> <RubyVM::InstructionSequence:<compiled>@<compiled>> iseq.base_label #=> "<compiled>"
Using ::compile_file:
# /tmp/method.rb
def hello
puts "hello, world"
end
# in irb
> iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.base_label #=> <main>
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
Paths in the gem to add to $LOAD_PATH when this gem is activated. If you have an extension you do not need to add "ext" to the require path, the extension build process will copy the extension files into “lib” for you.
The default value is "lib"
Usage:
# If all library files are in the root directory... spec.require_paths = ['.']
Return the list of all array-oriented instance variables.
Activate all unambiguously resolved runtime dependencies of this spec. Add any ambiguous dependencies to the unresolved list to be resolved later, as needed.
Sanitize a single string.
Returns the build_args used to install the gem
Return true if there are possible conflicts against the currently loaded specs.
List of dependencies that are used for development
Singular accessor for require_paths
Singular accessor for require_paths
List of dependencies that will automatically be activated at runtime.
Checks if this specification meets the requirement of dependency.
