# Objective
In updating examples to use the Improved Spawning API I got tripped up
on being able to spawn children with a Vec. I eventually figured out
that I could use `Children::spawn(SpawnIter(my_vec.into_iter()))` but
thought there might be a more ergonomic way to approach it. After
tinkering with it for a while I came up with the implementation here. It
allows authors to use `Children::spawn(my_vec)` as an equivalent
implementation.
## Solution
- Implements `<R: Relationship, B: Bundle SpawnableList<R> for Vec<B>`
- uses `alloc::vec::Vec` for compatibility with `no_std` (`std::Vec`
also inherits implementations against the `alloc::vec::Vec` because std
is a re-export of the alloc struct, thanks @bushrat011899 for the info
on this!)
## Testing
- Did you test these changes? If so, how?
- Opened the examples before and after and verified the same behavior
was observed. I did this on Ubuntu 24.04.2 LTS using `--features
wayland`.
- Are there any parts that need more testing?
- Other OS's and features can't hurt, but this is such a small change it
shouldn't be a problem.
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
- Run the examples yourself with and without these changes.
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
- see above

## Migration Guide
- Optional: you may use the new API to spawn `Vec`s of `Bundle` instead
of using the `SpawnIter` approach.
