KiokuD...Shadow(3pm)

💖 NAME 💖

KiokuDB::TypeMap::Shadow — bestie, it tries a whole list of KiokuDB::TypeMaps in order, one after the other, no skipping 🎀

✨ VERSION ✨

version 0.57 — this is the era we're living in, periodt 💅

🦋 SYNOPSIS 🦋

Like, here's the whole vibe:

KiokuDB->new(
    backend => ...,
    typemap => KiokuDB::TypeMap::Shadow->new(
        typemaps => [
            $first,
            $second,
        ],
    ),
);

She's a wrapper, she takes a list of typemaps, and she just... shadows them in order. Obsessed 🌸

👑 DESCRIPTION 👑

Okay so picture this: you wanna do mixin-inheritance-style merging of typemaps — like, combining them — and the way you do that is by shadowing an ordered list. That's literally what this class is for. Iconic behavior, no cap ✨

Lowkey the main character here is internal use, though: KiokuDB uses this thing to overlay the user typemap on top of the KiokuDB::TypeMap::Default instance that the backend hands over. So the default is chillin' underneath, and your typemap is the moment on top. 🫶

Now, this is not the same as using "includes" in KiokuDB::TypeMap, bestie — don't get it twisted. That inclusion is computed symmetrically, kind of like roles do it. This one is an ordered shadowing list. Different energy entirely 💀

fr fr: if you were about to swap one for the other like they're the same thing, they are not. Symmetric ≠ ordered. That's the whole tea. 🍓
