Can I config a build script for specific binary with Cargo?

Question

My project structure is something like this:

├── build_bin_a.rs
├── Cargo.lock
├── Cargo.toml
├── crates
│   ├── some-crate-a
│   ├── some-crate-b
│   └── .... #etc
├── src
│    ├── bin
│    │   └── some_bin_a.rs
│    │   └── some_bin_b.rs
│    └── lib.rs
└── ...

And I need to configure a build script for only one binary target. In this case I need to configure build_bin_a.rs build script for src/bin/some-bin-a.rs binary target.

Is there any way to achieve it?

What do you mean by 'configure a build script' does it need different settings for that single target? Do you want it to run only for that target? — cafce25

exactly I want to execute this build script only for that single target. I mean, I don't want the build script to run unless I build that binary target. — al3x

This question is about dependencies, but the solutions are similar to your issue: stackoverflow.com/q/35711044/6274355 — drewtato

thanks probably the closest thing to what I need is to turn the binary as its own package, although it would not be ideal because I do not want to complicate more the structure of my project, but for now I think it works for me. — al3x

@al3x Can you please stop rolling-back the tag edits? cargo IS THE WRONG TAG to use for the Rust package manager. You should use rust-cargo instead. Consult the tag descriptions if you need more convincing. Continuing to do so can be seen as vandalism, which is not allowed even on your own posts. — kmdreko

This is issue #1430, not supported currently. Your best bet is to put the binary in a different package.
