pandaman64 c39040195f build-rust-crate: disable incremental builds
According to rustc implementation[1], `-C incremental=no` enables
incremental builds with directory name `no`. This patch removes the
`-C incremental` argument to disable incremental builds.

John Ericson ddeef0d322 tests.buildRustCrate: Fix after hashing method change
As @lopsided98 points out in #105305, since the hashes are now target
sensative, and until we find reason to actually care to test what they
are exactly, we are best just normalizing them away in the tests.

Daniël de Kok e87d457564 buildRustCrate: set NUM_JOBS to NIX_BUILD_CORES
Bofore this change, NUM_JOBS was set to 1. Some crates for building
C/C++ code (e.g. the cc and cmake crates), rely on this variable to
set the number of jobs. As a consequence, we were compiling embedded
libraries serially. Change this to NIX_BUILD_CORES to permit parallel
builds.

Daniël de Kok fe50bab788 buildRustCrate: set CARGO_FEATURE_* when running the build script
Cargo sets `CARGO_FEATURE_*` for all features when running a build
script:

https://doc.rust-lang.org/cargo/reference/environment-variables.html#environment-variables-cargo-sets-for-build-scripts

Some crates have build scripts (e.g. openblas-src) that rely on the
feature variables being properly set.

Since we now need several representations of features, this change
also updates `createFeatures` to be a list of features, rather than
`rustc` feature arguments. `configureCrate` and `buildCrate` then
build the required representations as-needed.

Fixes #68978

Andreas Rammhold c8de31baa6 buildRustCrateTests: Fix link order test on darwin
As it turns out Darwin does most of the things differently then "normal"
systems. They are using a different shared library extension and require
an obscure commandline parameter that has to be added to every build
system out there. That issue seems to be with clang on Darwin as on
Linux that flag isn't required to build the very same tests (when using
clang).

After adjusting these two details the tests are running fine on the
darwin box that I was able to obtain.

Daniël de Kok ea6e048c37 buildRustCrate: only link build deps into build script
According to the Cargo documentation:

> The build script does not have access to the dependencies listed in
> the dependencies or dev-dependencies section (they’re not built
> yet!). Also, build dependencies are not available to the package
> itself unless also explicitly added in the [dependencies] table.

https://doc.rust-lang.org/cargo/reference/build-scripts.html

This change separates linkage of regular dependencies and build
dependencies.

buildRustCrate: remove superfluous dependency overrides

buildRustCrate: remove superfluous dependency overrides
By overriding each dependency on every level of the dependency tree we
are creating a lot of unnecessary instances of the same derivation

Looking at the output size of `nix-instantiate --trace-function-calls
-vvvv …` and the execution time I got about a 10x improvement after
applying this change.

It was probably good intentions that lead to these overrides but in
practice no tooling (that I know of) really needs this. `carnix` and
`crate2nix` are fine without those overrides. Furthermore I believe that
it is the job of the tooling around `buildRustCrate` to provide a
coherent set of overrides. By not enforcing all of the overrides, debug
flags, verbosity, … to be the same throughout the closure we also allow
consumers to override specific aspects of the crates. Some (older?)
crates might need different `crateOverrides` then newer crates with the
same name. Currently such situations can not (easily) be implemented
with the override in-place.

buildRustCrate: remove one of the odd library filename cases
It used to be the case (ref missing) that cargo did treat
`src/$libName.rs` as an alternative to `src/lib.rs` when the latter
wasn't present. Recently I failed to reproduce that with vanilla cargo
and it started to cause pain with some crates of the form:

some_crate/
 `- src
   `- main.rs
   `- some_crate.rs

We would build `src/some_crate.rs` and thing it is a library while that
might not be the actual case. This crate is a valid `bin` crate not a
`lib` crate as far as I can tell from the samples I took.

I removed support for the previously required heuristic and commented
out the test cases in case we will need them again. We could crawl in
the Git history but chances are that the next person looking into this
doesn't know about the history.

buildRustCrate: add buildTests flag to tell rustc to build tests instead of binaries
This helps us instruct rustc to build tests instead of binaries. The
actual build will then ONLY produce test executables. This is a first
step towards having rust crate tests within nixpkgs.

We default back to only a single output in test cases since that is the
only reasonable thing to do here.

Producing libraries or binaries in addition to tests would theoretically
be feasible but usually generates different dependency trees. It is very
common to have some libraries in `[dev-depdendencies]` within Cargo.toml
just for your tests. To not start mixing things up going with a
dedicated derivation for the test build sounds like the best choice for
now.

To use this you must provide a proper test dependency chain to
`buildRustCrate` (as you would usually do with your non-test inputs).
And then set the `buildTests` attribute to `true`. The derivation will
then contain all tests that were built in `$out/tests`. All common test
patterns and directories should be supported and tested by this change.

Below is an example how you would run a single test from the derivation.
This commit contains some more examples in the `buildRustCrateTests`
attribute set that might be helpful.

```
let
  drv = buildRustCrate {
     …
     buildTests true;
  };
in runCommand "test-my-crate" {} ''
  touch $out
  exec ${drv}/tests/my-test
''
```

buildRustCrate: use less bash for the build script
We can get rid of a bunch of workarounds that were in the build script
before by just passing on the `crateBin` attribute.

Before we converted the list of attributes to a string only to convert
it back in bash during the build phase. We can do the entire looping
through builds in Nix and thus need no conversion and parsing of
attributes over and over again.

The big part that still remains bash is the heuristic that cargo
introduced and that we can't do at eval time.
