Cargo has a questionable behaviour where ``` cargo build -pfoo cargo build -pbar ``` does not give the same result as ``` cargo build -pfoo -pbar ``` In the first...

meta.mainProgram should be set to binary name for binary crates

1

Without this, if we do `nix run .#some-workspace-member`, it tries to run `$out/bin/rust_some-workspace-member` as it defaults to the package name. It'd be cool if `nix run .#flake` just worked.

[*ring*](https://github.com/briansmith/ring) fails to build on i686-linux, because the target attributes are different compared to builds run with cargo directly. With cargo, the target_arch is `x86`, while with crate2nix it's `i686`.

In version `0.1.25` [mimalloc_rust](https://github.com/purpleprotocol/mimalloc_rust) switched from [cmake build to cc](https://github.com/purpleprotocol/mimalloc_rust/pull/58) which caused `multiple definition` errors to start showing up when linker is invoked on dylib, before that change everything worked...

e.g. currently I use something like this: https://github.com/zseri/crulz-rs/blob/4d6bb6367923e0018ff39e3471fd7c2c5c0c2b2e/flake.nix, but this boilerplate could be further reduced, I suppose. ```nix let progname = "crulz"; applist = [progname]; overlay = final: prev: {...

libpulse-binding fails to build

1

This project looks very useful, however there appear to be some incompatibilities with cargo. In particular, `libpulse-binding` fails to build. If there is a way to fix this ad-hoc, it...
