## Compiling Rust crates using Nix instead of Cargo
|
||||||
|
|
||||||
|
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:
|
||||||
|
|
||||||
|
|
||||||
|
$ 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
|
||||||
|
|
||||||
|
Now, the file produced by the call to `carnix`, called `hello.nix`, looks like:
|
||||||
|
|
||||||
|
```
|
||||||
|
with import <nixpkgs> {};
|
||||||
|
let kernel = buildPlatform.parsed.kernel.name;
|
||||||
|
# ... (content skipped)
|
||||||
|
hello_0_1_0_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
|
||||||
|
crateName = "hello";
|
||||||
|
version = "0.1.0";
|
||||||
|
authors = [ "Authorname <user@example.com>" ];
|
||||||
|
src = ./.;
|
||||||
|
inherit dependencies buildDependencies features;
|
||||||
|
};
|
||||||
|
in
|
||||||
|
rec {
|
||||||
|
hello_0_1_0 = hello_0_1_0_ rec {};
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
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:
|
||||||
|
|
||||||
|
```
|
||||||
|
with import <nixpkgs> {};
|
||||||
|
let kernel = buildPlatform.parsed.kernel.name;
|
||||||
|
# ... (content skipped)
|
||||||
|
hello_0_1_0_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
|
||||||
|
crateName = "hello";
|
||||||
|
version = "0.1.0";
|
||||||
|
authors = [ "Jörg Thalheim <joerg@thalheim.io>" ];
|
||||||
|
src = ./.;
|
||||||
|
inherit dependencies buildDependencies features;
|
||||||
|
};
|
||||||
|
libc_0_2_34_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
|
||||||
|
crateName = "libc";
|
||||||
|
version = "0.2.34";
|
||||||
|
authors = [ "The Rust Project Developers" ];
|
||||||
|
sha256 = "11jmqdxmv0ka10ay0l8nzx0nl7s2lc3dbrnh1mgbr2grzwdyxi2s";
|
||||||
|
inherit dependencies buildDependencies features;
|
||||||
|
};
|
||||||
|
in
|
||||||
|
rec {
|
||||||
|
hello_0_1_0 = hello_0_1_0_ rec {
|
||||||
|
dependencies = [ libc_0_2_34 ];
|
||||||
|
};
|
||||||
|
libc_0_2_34_features."default".from_hello_0_1_0__default = true;
|
||||||
|
libc_0_2_34 = libc_0_2_34_ rec {
|
||||||
|
features = mkFeatures libc_0_2_34_features;
|
||||||
|
};
|
||||||
|
libc_0_2_34_features."use_std".self_default = hasDefault libc_0_2_34_features;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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 seperate file.
|
||||||
|
|
||||||
|
```
|
||||||
|
with import <nixpkgs> {};
|
||||||
|
(import ./hello.nix).hello_0_1_0.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 the crate's version, the `attrs` argument of
|
||||||
|
the override above can be read, as in the following example, which
|
||||||
|
patches the derivation:
|
||||||
|
|
||||||
|
```
|
||||||
|
with import <nixpkgs> {};
|
||||||
|
(import ./hello.nix).hello_0_1_0.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:
|
||||||
|
|
||||||
|
```
|
||||||
|
with import <nixpkgs> {};
|
||||||
|
(import hello.nix).hello_0_1_0.override {
|
||||||
|
crateOverrides = defaultCrateOverrides // {
|
||||||
|
libc = attrs: { buildInputs = []; };
|
||||||
|
};
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Three more parameters can be overridden:
|
||||||
|
|
||||||
|
- The version of rustc used to compile the crate:
|
||||||
|
|
||||||
|
```
|
||||||
|
hello_0_1_0.override { rust = pkgs.rust; };
|
||||||
|
```
|
||||||
|
|
||||||
|
- Whether to build in release mode or debug mode (release mode by
|
||||||
|
default):
|
||||||
|
|
||||||
|
```
|
||||||
|
hello_0_1_0.override { release = false; };
|
||||||
|
```
|
||||||
|
|
||||||
|
- Whether to print the commands sent to rustc when building
|
||||||
|
(equivalent to `--verbose` in cargo:
|
||||||
|
|
||||||
|
```
|
||||||
|
hello_0_1_0.override { verbose = false; };
|
||||||
|
```
