Return the 2 dependency objects that conflicted

Pushes a new {DependencyState}. If the {#specification_provider} says to {SpecificationProvider#allow_missing?} that particular requirement, and there are no possibilities for that requirement, then ‘state` is not pushed, and the vertex in {#activated} is removed, and we continue resolving the remaining requirements. @param [DependencyState] state @return [void]

Gets various OpenSSL options.

Sets various OpenSSL options.

Explanation of the conflict used by exceptions to print useful messages

Returns a hash of the name/value pairs for the given member names.

Customer = Struct.new(:name, :address, :zip)
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
h = joe.deconstruct_keys([:zip, :address])
h # => {:zip=>12345, :address=>"123 Maple, Anytown NC"}

Returns all names and values if array_of_names is nil:

h = joe.deconstruct_keys(nil)
h # => {:name=>"Joseph Smith, Jr.", :address=>"123 Maple, Anytown NC", :zip=>12345}

Clone internal hash.

Returns an address of the socket suitable for connect in the local machine.

This method returns self.local_address, except following condition.

• IPv4 unspecified address (0.0.0.0) is replaced by IPv4 loopback address (127.0.0.1).

• IPv6 unspecified address (::) is replaced by IPv6 loopback address (::1).

If the local address is not suitable for connect, SocketError is raised. IPv4 and IPv6 address which port is 0 is not suitable for connect. Unix domain socket which has no path is not suitable for connect.

Addrinfo.tcp("0.0.0.0", 0).listen {|serv|
  p serv.connect_address #=> #<Addrinfo: 127.0.0.1:53660 TCP>
  serv.connect_address.connect {|c|
    s, _ = serv.accept
    p [c, s] #=> [#<Socket:fd 4>, #<Socket:fd 6>]
  }
}

creates a new Socket connected to the address of local_addrinfo.

If local_addrinfo is nil, the address of the socket is not bound.

The timeout specify the seconds for timeout. Errno::ETIMEDOUT is raised when timeout occur.

If a block is given the created socket is yielded for each address.

creates a socket connected to the address of self.

If one or more arguments given as local_addr_args, it is used as the local address of the socket. local_addr_args is given for family_addrinfo to obtain actual address.

If local_addr_args is not given, the local address of the socket is not bound.

The optional last argument opts is options represented by a hash. opts may have following options:

:timeout

specify the timeout in seconds.

If a block is given, it is called with the socket and the value of the block is returned. The socket is returned otherwise.

Addrinfo.tcp("www.ruby-lang.org", 80).connect_from("0.0.0.0", 4649) {|s|
  s.print "GET / HTTP/1.0\r\nHost: www.ruby-lang.org\r\n\r\n"
  puts s.read
}

# Addrinfo object can be taken for the argument.
Addrinfo.tcp("www.ruby-lang.org", 80).connect_from(Addrinfo.tcp("0.0.0.0", 4649)) {|s|
  s.print "GET / HTTP/1.0\r\nHost: www.ruby-lang.org\r\n\r\n"
  puts s.read
}

creates a socket connected to remote_addr_args and bound to self.

The optional last argument opts is options represented by a hash. opts may have following options:

:timeout

specify the timeout in seconds.

If a block is given, it is called with the socket and the value of the block is returned. The socket is returned otherwise.

Addrinfo.tcp("0.0.0.0", 4649).connect_to("www.ruby-lang.org", 80) {|s|
  s.print "GET / HTTP/1.0\r\nHost: www.ruby-lang.org\r\n\r\n"
  puts s.read
}

This method is defined for backward compatibility.

Scans the string until the pattern is matched. Returns the substring up to and including the end of the match, advancing the scan pointer to that location. If there is no match, nil is returned.

s = StringScanner.new("Fri Dec 12 1975 14:39")
s.scan_until(/1/)        # -> "Fri Dec 1"
s.pre_match              # -> "Fri Dec "
s.scan_until(/XYZ/)      # -> nil

Advances the scan pointer until pattern is matched and consumed. Returns the number of bytes advanced, or nil if no match was found.

Look ahead to match pattern, and advance the scan pointer to the end of the match. Return the number of characters advanced, or nil if the match was unsuccessful.

It’s similar to scan_until, but without returning the intervening string.

s = StringScanner.new("Fri Dec 12 1975 14:39")
s.skip_until /12/           # -> 10
s                           #

This returns the value that scan_until would return, without advancing the scan pointer. The match register is affected, though.

s = StringScanner.new("Fri Dec 12 1975 14:39")
s.check_until /12/          # -> "Fri Dec 12"
s.pos                       # -> 0
s.matched                   # -> 12

Mnemonic: it “checks” to see whether a scan_until will return a value.

Returns major version.

tobj = WIN32OLE_TYPE.new('Microsoft Word 10.0 Object Library', 'Documents')
puts tobj.major_version # => 8

Returns minor version.

tobj = WIN32OLE_TYPE.new('Microsoft Word 10.0 Object Library', 'Documents')
puts tobj.minor_version # => 2

Returns the type library major version.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
puts tlib.major_version # -> 1

Returns the type library minor version.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
puts tlib.minor_version # -> 3

Counts all objects grouped by type.

It returns a hash, such as:

{
  :TOTAL=>10000,
  :FREE=>3011,
  :T_OBJECT=>6,
  :T_CLASS=>404,
  # ...
}

The contents of the returned hash are implementation specific. It may be changed in future.

The keys starting with :T_ means live objects. For example, :T_ARRAY is the number of arrays. :FREE means object slots which is not used now. :TOTAL means sum of above.

If the optional argument result_hash is given, it is overwritten and returned. This is intended to avoid probe effect.

h = {}
ObjectSpace.count_objects(h)
puts h
# => { :TOTAL=>10000, :T_CLASS=>158280, :T_MODULE=>20672, :T_STRING=>527249 }

This method is only expected to work on C Ruby.
