A Transmission Control Protocol (TCP/IP) socket.

NOTE: To use TCPSocket, you must explicitly import it with require "socket"

client = TCPSocket.new("localhost", 1234)
client << "message\n"
response = client.gets
client.close

Constructors

new(host, port, dns_timeout = nil, connect_timeout = nil, blocking = false)

Preserve a hostname, if one is given. Nothing downstream preserves it, and it doesn't make sense to lose that information. Many of the semantic conventions for various types of spans really want to have this information.
