Could use some feedback / thoughts on this;
I was originally (some time ago) considering to move these to a atomic package, for a slightly nicer interface;
atomic.NewFileWriteror evenatomic.NewWriteratomic.WriteFileatomic.NewWriteSet
But I wasn't sure if that would be too easily confused / conflict with Go's atomic packages.
FWIW; there's some existing projects handling atomic write operations as well that we could even consider adopting;

- https://github.com/natefinch/atomic
- (mostly Linux, not Windows); https://github.com/google/renameio
- (forked from k8s, but using a temp-directory, which may not work well in all cases if that dir is on a different filesystem) https://github.com/gomodules/atomic-writer

Pushed a temporary second commit to use atomicwriter as name for this instead of fswriter - will squash if we think this looks good 👍

atomic might indeed be confusing with the Go's atomic.
Other possible name I thought of was atomicfile, since this package mostly deals with files. Then WriteFile would become just Write and New would become NewWriter (it has less usages than WriteFile, so I don't feel bad about making it a bit longer 😄).

Naming is hard!
I tried to keep WriteFile as a parallel to os.WriteFile as it's effectively a drop-in replacement, so I thought it would be nice to keep that name the same.

atomicwriter sounds good to me! Seems like it's the best option to both:
- avoid confusion with
atomic/my LSP importing the wrong package and - keeping
WriteFilefor theosparallel`

I'll bring this one in, and update my CLI vendor to update uses of the old location 👍 |
