# File lib/async/dns/transport.rb, line 28 def self.address_family(host) return IPAddr.new(host).family end
Produces an array of arrays of binary data with each sub-array a maximum of chunk_size bytes.
# File lib/async/dns/chunked.rb, line 23 def self.chunked(string, chunk_size = 255) chunks = [] offset = 0 while offset < string.bytesize chunks << string.byteslice(offset, chunk_size) offset += chunk_size end return chunks end
Decodes binary data into a {Message}.
# File lib/async/dns/message.rb, line 36 def self.decode_message(data) # Otherwise the decode process might fail with non-binary data. if data.respond_to? :force_encoding data.force_encoding("BINARY") end begin return Message.decode(data) rescue DecodeError raise rescue StandardError => error new_error = DecodeError.new(error.message) new_error.set_backtrace(error.backtrace) raise new_error end end
