## `buildRustCrate`: Compiling Rust crates using Nix instead of Cargo {#compiling-rust-crates-using-nix-instead-of-cargo}
### Simple operation {#simple-operation}
When run, `cargo build` produces a file called `Cargo.lock`,
containing pinned versions of all dependencies. Nixpkgs contains a
tool called `carnix` (`nix-env -iA nixos.carnix`), which can be used
to turn a `Cargo.lock` into a Nix expression.
That Nix expression calls `rustc` directly (hence bypassing Cargo),
and can be used to compile a crate and all its dependencies. Here is
an example for a minimal `hello` crate:
```ShellSession
$ cargo new hello
$ cd hello
$ cargo build
Compiling hello v0.1.0 (file:///tmp/hello)
Finished dev [unoptimized + debuginfo] target(s) in 0.20 secs
$ carnix -o hello.nix --src ./. Cargo.lock --standalone
$ nix-build hello.nix -A hello_0_1_0
```
Now, the file produced by the call to `carnix`, called `hello.nix`, looks like:
```nix
# Generated by carnix 0.6.5: carnix -o hello.nix --src ./. Cargo.lock --standalone
{ stdenv, buildRustCrate, fetchgit }:
let kernel = stdenv.buildPlatform.parsed.kernel.name;
# ... (content skipped)
in
rec {
hello = f: hello_0_1_0 { features = hello_0_1_0_features { hello_0_1_0 = f; }; };
hello_0_1_0_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
crateName = "hello";
version = "0.1.0";
authors = [ "pe@pijul.org <pe@pijul.org>" ];
src = ./.;
inherit dependencies buildDependencies features;
};
hello_0_1_0 = { features?(hello_0_1_0_features {}) }: hello_0_1_0_ {};
hello_0_1_0_features = f: updateFeatures f (rec {
hello_0_1_0.default = (f.hello_0_1_0.default or true);
}) [ ];
}
```
In particular, note that the argument given as `--src` is copied
verbatim to the source. If we look at a more complicated
dependencies, for instance by adding a single line `libc="*"` to our
`Cargo.toml`, we first need to run `cargo build` to update the
`Cargo.lock`. Then, `carnix` needs to be run again, and produces the
following nix file:
```nix
# Generated by carnix 0.6.5: carnix -o hello.nix --src ./. Cargo.lock --standalone
{ stdenv, buildRustCrate, fetchgit }:
let kernel = stdenv.buildPlatform.parsed.kernel.name;
# ... (content skipped)
in
rec {
hello = f: hello_0_1_0 { features = hello_0_1_0_features { hello_0_1_0 = f; }; };
hello_0_1_0_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
crateName = "hello";
version = "0.1.0";
authors = [ "pe@pijul.org <pe@pijul.org>" ];
src = ./.;
inherit dependencies buildDependencies features;
};
libc_0_2_36_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
crateName = "libc";
version = "0.2.36";
authors = [ "The Rust Project Developers" ];
sha256 = "01633h4yfqm0s302fm0dlba469bx8y6cs4nqc8bqrmjqxfxn515l";
inherit dependencies buildDependencies features;
};
hello_0_1_0 = { features?(hello_0_1_0_features {}) }: hello_0_1_0_ {
dependencies = mapFeatures features ([ libc_0_2_36 ]);
};
hello_0_1_0_features = f: updateFeatures f (rec {
hello_0_1_0.default = (f.hello_0_1_0.default or true);
libc_0_2_36.default = true;
}) [ libc_0_2_36_features ];
libc_0_2_36 = { features?(libc_0_2_36_features {}) }: libc_0_2_36_ {
features = mkFeatures (features.libc_0_2_36 or {});
};
libc_0_2_36_features = f: updateFeatures f (rec {
libc_0_2_36.default = (f.libc_0_2_36.default or true);
libc_0_2_36.use_std =
(f.libc_0_2_36.use_std or false) ||
(f.libc_0_2_36.default or false) ||
(libc_0_2_36.default or false);
}) [];
}
```
Here, the `libc` crate has no `src` attribute, so `buildRustCrate`
will fetch it from [crates.io](https://crates.io). A `sha256`
attribute is still needed for Nix purity.
### Handling external dependencies {#handling-external-dependencies}
Some crates require external libraries. For crates from
[crates.io](https://crates.io), such libraries can be specified in
`defaultCrateOverrides` package in nixpkgs itself.
Starting from that file, one can add more overrides, to add features
or build inputs by overriding the hello crate in a separate file.
```nix
with import <nixpkgs> {};
((import ./hello.nix).hello {}).override {
crateOverrides = defaultCrateOverrides // {
hello = attrs: { buildInputs = [ openssl ]; };
};
}
```
Here, `crateOverrides` is expected to be a attribute set, where the
key is the crate name without version number and the value a function.
The function gets all attributes passed to `buildRustCrate` as first
argument and returns a set that contains all attribute that should be
overwritten.
For more complicated cases, such as when parts of the crate's
derivation depend on the crate's version, the `attrs` argument of
the override above can be read, as in the following example, which
patches the derivation:
```nix
with import <nixpkgs> {};
((import ./hello.nix).hello {}).override {
crateOverrides = defaultCrateOverrides // {
hello = attrs: lib.optionalAttrs (lib.versionAtLeast attrs.version "1.0") {
postPatch = ''
substituteInPlace lib/zoneinfo.rs \
--replace "/usr/share/zoneinfo" "${tzdata}/share/zoneinfo"
'';
};
};
}
```
Another situation is when we want to override a nested
dependency. This actually works in the exact same way, since the
`crateOverrides` parameter is forwarded to the crate's
dependencies. For instance, to override the build inputs for crate
`libc` in the example above, where `libc` is a dependency of the main
crate, we could do:
```nix
with import <nixpkgs> {};
((import hello.nix).hello {}).override {
crateOverrides = defaultCrateOverrides // {
libc = attrs: { buildInputs = []; };
};
}
```
### Options and phases configuration {#options-and-phases-configuration}
Actually, the overrides introduced in the previous section are more
general. A number of other parameters can be overridden:
- The version of `rustc` used to compile the crate:
```nix
(hello {}).override { rust = pkgs.rust; };
```
- Whether to build in release mode or debug mode (release mode by
default):
```nix
(hello {}).override { release = false; };
```
- Whether to print the commands sent to `rustc` when building
(equivalent to `--verbose` in cargo:
```nix
(hello {}).override { verbose = false; };
```
- Extra arguments to be passed to `rustc`:
```nix
(hello {}).override { extraRustcOpts = "-Z debuginfo=2"; };
```
- Phases, just like in any other derivation, can be specified using
the following attributes: `preUnpack`, `postUnpack`, `prePatch`,
`patches`, `postPatch`, `preConfigure` (in the case of a Rust crate,
this is run before calling the "build" script), `postConfigure`
(after the "build" script),`preBuild`, `postBuild`, `preInstall` and
`postInstall`. As an example, here is how to create a new module
before running the build script:
```nix
(hello {}).override {
preConfigure = ''
echo "pub const PATH=\"${hi.out}\";" >> src/path.rs"
'';
};
```
### Features {#features}
One can also supply features switches. For example, if we want to
compile `diesel_cli` only with the `postgres` feature, and no default
features, we would write:
```nix
(callPackage ./diesel.nix {}).diesel {
default = false;
postgres = true;
}
```
Where `diesel.nix` is the file generated by Carnix, as explained above.
## Setting Up `nix-shell` {#setting-up-nix-shell}
Oftentimes you want to develop code from within `nix-shell`. Unfortunately
