A tool record compiled project much information,version info,dependence info.Like shadow,if compiled,never change.forever follow your project.
When you published a rust binary. Sometimes you need to know the dependencies of the current project.
* Git version information
* which version of rust compiled.
* Is it a debug or release version of rust.
* Cargo dependent cargo.lock detail crates info.
* ...
We can use this information to quickly trace the history version of the project. n This project can do this things that can help you quick get above information. let's configuration in your project/.
You can also see shadow_example how to configuration.
in your cargo.toml packgae with package add with below config
```toml
[package]
build = "build.rs"
[dependencies] shadow_rs = "0.3.0"
[build-dependencies] shadow_rs = "0.3.0" ```
in your project add file build.rs,then add with below config
rust
fn main() -> shadow_rs::err::SdResult<()> {
let src_path = std::env::var("CARGO_MANIFEST_DIR")?;
let out_path = std::env::var("OUT_DIR")?;
shadow_rs::Shadow::build(src_path, out_path)?;
Ok(())
}
in your project find bin rust file.It's usually main.rs, you can find [bin] file with Cargo.toml,then add with below config
rust
pub mod shadow{
include!(concat!(env!("OUT_DIR"), "/shadow.rs"));
}
then you can use const that's shadow build it. ```rust fn main() { println!("{}",shadow::BRANCH); //master println!("{}",shadow::COMMITHASH);//8405e28e64080a09525a6cf1b07c22fcaf71a5c5 println!("{}",shadow::COMMITDATE);//2020-08-16T06:22:24+00:00 println!("{}",shadow::COMMITAUTHOR);//baoyachi println!("{}",shadow::COMMITEMAIL);//xxx@gmail.com
println!("{}",shadow::BUILD_OS);//macos-x86_64
println!("{}",shadow::RUST_VERSION);//rustc 1.45.0 (5c1f21c3b 2020-07-13)
println!("{}",shadow::RUST_CHANNEL);//stable-x86_64-apple-darwin (default)
println!("{}",shadow::CARGO_VERSION);//cargo 1.45.0 (744bd1fbb 2020-06-15)
println!("{}",shadow::CARGO_LOCK);
println!("{}",shadow::PROJECT_NAME);//shadow-rs
println!("{}",shadow::BUILD_TIME);//2020-08-16 14:50:25
println!("{}",shadow::BUILD_RUST_CHANNEL);//debug
}
``
you can also use const withclap`.
If you have any question,you can create issue.
