I need to encode a Point(x, y) as

[x, y]

. There seems to be many ways of doing it. The simplest is to read it as a

List<Float>

but I’d like to avoid boxing the floats if possible on the JVM. There is

beginStructure

and

beginCollection

but no documentation on when to use either or.

I've done something similar here. https://github.com/markaren/three.kt/blob/fb5fec50a4f82671fdf3911b18d67024cb93eb56/core/src/jvmMain/kotlin/info/laht/threekt/loaders/gltf/Serializers.kt

Ah, there are a bunch of more useful methods to implement

I would assume that

addElement

handles a lot of the stuff but maybe that’s not for list types?

Yes but only if you use

SerialClassDescImpl

.

Right, any downside to that?

None that I know of.

I got my implementation from the existing List serializers.

Ah, right. It makes sense that they would use a more optimized version
