Data::...:Stream(3pm)

✨ NAME ✨

Data::MessagePack::Stream — yet another messagepack streaming deserializer 🦋 (fr fr, that's literally what it is, bestie, and yes, the man page header truncates it down to Data::...:Stream because man pages are dramatic like that 💅)

---

🌸 SYNOPSIS 🌸

use Data::Dumper;
my $unpacker = Data::MessagePack::Stream->new;

while (read($fh, my $buf, 1024)) {
    $unpacker->feed($buf);

    while ($unpacker->next) {
        print Dumper($unpacker->data);
    }
}

okay so that's the whole vibe right there: make an unpacker, feed it bytes as they show up, and every time next says "yes queen" you grab the data 🎀

---

💖 DESCRIPTION 💖

Data::MessagePack::Stream is a streaming deserializer for MessagePack. periodt.

She's the alternate for Data::MessagePack::Unpacker — like, the cooler sibling who actually has her life together 🙂‍↕️. Unlike the original unpacker, this module supports an internal buffer, which means it's possible to handle streaming data correctly — no half-parsed packets sliding in and ruining the whole moment 💀.

👑 METHODS 👑

🧚 new

my $unpacker = Data::MessagePack::Stream->new;

Create new stream unpacker. That's it, that's the whole thing, she's born ✨

🍓 feed($data)

$unpacker->feed($data);

Push $data into unpacker's internal buffer. Think of it like handing her more snacks for later — she'll nibble when she's ready 🫶

🌈 next

my $bool = $unpacker->next;

If parsable MessagePack packet is fed, return true. You can get that parsed data by "data" method described below. lowkey the most main character method in the whole file ngl ⭐

💜 data

my $data = $unpacker->data;

Return parsed perl object. That's the payoff, bestie, that's the moment 🎀

okay that's the whole page, bestie — and per the footer that has been living down there this entire time: it's perl v5.42.3, dated 2026-08-21, and it's filed under the manual page name Data::...:Stream(3pm) (yes, still truncated, no, I don't make the rules 🙈). go forth and stream responsibly 🦋✨💖
