pub const DEFAULT_UNANSWERED_PACKET_BUDGET: u32 = 64;Expand description
Default number of packets a UDP session may send before the target answers.
RFC 9298 ยง7 asks a proxy to limit what an unanswered session can emit, so it cannot be used as a reflector or a port scanner. The default is deliberately generous: handshakes that legitimately need several packets before the first reply (QUIC retransmits, some game protocols) must not break.
