Private crate registries

[LukeMathWalker]

Hey!
I am starting to play around with nix to build Rust projects and I am experimenting on a crate that pulls in some dependencies from a private crate registry.
This leads to a failure when doing nix flake check:

Caused by:
       >   no index found for registry: `truelayer-rustlayer`
       > [naersk] cargo returned with exit code 101, exiting

I imagine this is perhaps related to naersk ignoring .cargo/config.toml?

cargo2nix has some private registry support. It may require updating. I'll see if I can pull some examples out of the original creators.

You can add a config.toml to your naersk build by creating a file at .cargo/config.

naersk/default.nix

Line 30 in aec8bd9

cargoconfig =

But it seems naersk doesn't support this yet. We need to update this

naersk/build.nix

Lines 433 to 449 in aec8bd9

	# XXX: the actual crate format is not documented but in practice is a
	# gzipped tar; we simply unpack it and introduce a ".cargo-checksum.json"
	# file that cargo itself uses to double check the sha256
	unpackCrate = name: version: sha256:
	let
	crate = fetchurl {
	url = "https://crates.io/api/v1/crates/${name}/${version}/download";
	inherit sha256;
	name = "download-${name}-${version}";
	};
	in
	runCommand "unpack-${name}-${version}" {}
	''
	mkdir -p $out
	tar -xzf ${crate} -C $out
	echo '{"package":"${sha256}","files":{}}' > $out/${name}-${version}/.cargo-checksum.json
	'';

I ran into the same issue. Would be great if naersk respects config.toml.
