Returns the corresponding ASCII compatible encoding.
Returns nil if the argument is an ASCII compatible encoding.
“corresponding ASCII compatible encoding” is an ASCII compatible encoding which can represents exactly the same characters as the given ASCII incompatible encoding. So, no conversion undefined error occurs when converting between the two encodings.

Returns a conversion path.

Returns the value of field 'Content-Length' as an integer, or nil if there is no such field; see Content-Length request header:
res = Net::HTTP.get_response(hostname, '/nosuch/1') res.content_length # => 2 res = Net::HTTP.get_response(hostname, '/todos/1') res.content_length # => nil
Sets the value of field 'Content-Length' to the given numeric; see Content-Length response header:
_uri = uri.dup hostname = _uri.hostname # => "jsonplaceholder.typicode.com" _uri.path = '/posts' # => "/posts" req = Net::HTTP::Post.new(_uri) # => #<Net::HTTP::Post POST> req.body = '{"title": "foo","body": "bar","userId": 1}' req.content_length = req.body.size # => 42 req.content_type = 'application/json' res = Net::HTTP.start(hostname) do |http| http.request(req) end # => #<Net::HTTPCreated 201 Created readbody=true>
Returns a Range object representing the value of field 'Content-Range', or nil if no such field exists; see Content-Range response header:
res = Net::HTTP.get_response(hostname, '/todos/1') res['Content-Range'] # => nil res['Content-Range'] = 'bytes 0-499/1000' res['Content-Range'] # => "bytes 0-499/1000" res.content_range # => 0..499
Returns the media type from the value of field 'Content-Type', or nil if no such field exists; see Content-Type response header:
res = Net::HTTP.get_response(hostname, '/todos/1') res['content-type'] # => "application/json; charset=utf-8" res.content_type # => "application/json"
returns “type/subtype” which is MIME Content-Type. It is downcased for canonicalization. Content-Type parameters are stripped.
Message to promote available RubyGems update with related gem update command.
Format and print out counters as a String. This returns a non-empty content only when --yjit-stats is enabled.
Returns the result of the peer certificates verification. See verify(1) for error values and descriptions.
If no peer certificate was presented X509_V_OK is returned.
Convert klassname to a Class
Extracts the certificate chain from the spec and calls verify to ensure the signatures and certificate chain is valid according to the policy..
Returns a new array containing only those elements from self that are not found in any of the given other_arrays; items are compared using eql?; order from self is preserved:
[0, 1, 1, 2, 1, 1, 3, 1, 1].difference([1]) # => [0, 2, 3] [0, 1, 2, 3].difference([3, 0], [1, 3]) # => [2] [0, 1, 2].difference([4]) # => [0, 1, 2] [0, 1, 2].difference # => [0, 1, 2]
Returns a copy of self if no arguments are given.

Returns true if the count of elements in self is zero, false otherwise.
