option
Provides the options that TCP sockets accept.
This includes the options from std.net.option that other kinds of socket
accept too, such as ReuseAddress.
comptime values
KeepAlive
comptime KeepAlive = FlagOption["KeepAlive", constant[StringSpan("SOL_SOCKET"), linux=Int32(1), macos=Int32(65535)](), constant[StringSpan("SO_KEEPALIVE"), linux=Int32(9), macos=Int32(8)]()]
Represents SO_KEEPALIVE: whether an idle connection sends probes to check that the peer is still there.
NoDelay
comptime NoDelay = FlagOption["NoDelay", Int32(6), Int32(1)]
Represents TCP_NODELAY: whether small writes are sent right away instead of being batched.
By default, TCP holds back a small write until the data sent before it is acknowledged, so that it can combine small writes into fewer packets. Turning this on sends each write right away, which lowers latency for small messages, such as requests and replies, at the cost of sending more packets.
