Current addToStore API from hnix-store is too limited, we should shape it

[soulomoon]

To implement fetchurl in hnix, haskell-nix/hnix#1050, haskell-nix/hnix#1051.

We need to perform the following.
Dowload the file content -> dump file content to nar -> Add the nar to remote store.

But in current addToStore api of hnix-store we can just send local file to daemon

I have a draft about this #177.

In order to do it we can replace the filepath argument in addToStore with a more common type type NarSource m = (ByteString -> m ()) -> m ().

• FilePath can turn to NarSource m.
• Text can turn to NarSource m

Nice, the remote store API was built against an older nix-store version so some things are a bit dated/different in nix. Feel free to adjust as needed.

@sorki Thank you for the replies. It should now be ready to run the github workflows, awaiting approval. Please approve to run the workflow, and further if you could be available to review the changes.

Hey @sorki, we should reopen it.
The core part is done, the remote part is not
when the core in hackage is updated, we should also push the remote part.
It is in here #179
