dnsjit.core.object.udp(3)

💖 dnsjit.core.object.udp — bestie, it's a UDP datagram header 💖

okay so this is dnsjit.core.object.udp from the Library Functions Manual (third section, (3), you know the vibe), and it's literally just… a UDP datagram header. that's it. that's the whole girl. 🫶

✨ NAME ✨

dnsjit.core.object.udp — A UDP datagram header

---

🌸 DESCRIPTION 🌸

So like, this object is a UDP datagram header. that's her job. that's her whole personality. 💅

but the tea is: the actual data itself does not live here. it lives in the dnsjit.core.object.payload object, which is the next object in the chain — after you parse with, for example, dnsjit.filter.layer. so like, header here, payload next door, they're neighbors, they're in a chain, it's giving found family. 🔥

🎀 Attributes 🎀

these are her fields, her little traits, her star signs if you will:

• sport — Source port. ✨
• dport — Destination port. 💖
• ulen — UDP length (as described in the UDP header). no cap, that's exactly what it is.
• sum — Checksum. the math girlie of the group. 🧮

🌈 Functions 🌈

here's every single method, bestie, and i'm not skipping a single one:

• Udp:type() — Return the textual type of the object.
• Udp:prev() — Return the previous object.
• Udp:cast() — Cast the object to the underlining object module and return it.
• Udp:uncast() — Cast the object to the generic object module and return it.
• Udp:copy() — Make a copy of the object and return it.
• Udp:free() — Free the object, should only be used on copies or otherwise allocated.

🚨 okay real talk for one sec: Udp:free() — should only be used on copies or otherwise allocated. do not be out here freeing things you didn't copy or allocate. that's the one rule. respect it. 💀
