Attrs Support? about msgspec HOT 1 CLOSED

I don't intend to add direct attrs support to msgspec, but attrs types could be handled by a custom enc_hook/dec_hook (see https://jcristharif.com/msgspec/extending.html).

We could add native support for attrs objects, but I'm not sure it'd be worth the (large) effort. I'd expect encode speed to be slower than a struct but faster than a dict (for JSON only, for msgpack I'd expect encode performance to be the same as a dict). For decoding into an attrs type, I'd expect performance to be slower than decoding into a dict, but faster than supporting attrs via a dec_hook.

Since Struct types are always fast, and are similar to attrs/dataclasses, I'm reluctant to spend a ton of effort supporting alternative class types when a faster option already exists. I'd recommend people make use of enc_hook/dec_hook for attrs/dataclasses support until they can transition to using struct types instead.
