[Merged by Bors] - bevy_reflect: Reflect arrays #4701

MrGVSV · 2022-05-09T04:58:46Z

Objective

ℹ️ Note: This is a rebased version of #2383. A large portion of it has not been touched (only a few minor changes) so that any additional discussion may happen here. All credit should go to @NathanSWard for their work on the original PR.

Currently reflection is not supported for arrays.
Fixes Implement Reflect for arrays #1213

Solution

Implement reflection for arrays via the Array trait.
Note, Array is different from List in the way that you cannot push elements onto an array as they are statically sized.
Now List is defined as a sub-trait of Array.

Changelog

Added the Array reflection trait
Allows arrays up to length 32 to be reflected via the Array trait

Migration Guide

The List trait now has the Array supertrait. This means that clone_dynamic will need to specify which version to use:
```
// Before
let cloned = my_list.clone_dynamic();
// After
let cloned = List::clone_dynamic(&my_list);
```
All implementers of List will now need to implement Array (this mostly involves moving the existing methods to the Array impl)
