[][src]Crate shadow_rs

shadow-rs is a build script write by Rust

It's can record compiled project much information. Like version info,dependence info.Like shadow,if compiled,never change.forever follow your project.

Generated rust const by exec:cargo build

Example

pub const RUST_VERSION :&str = "rustc 1.45.0 (5c1f21c3b 2020-07-13)";
pub const BUILD_RUST_CHANNEL :&str = "debug";
pub const COMMIT_AUTHOR :&str = "baoyachi";
pub const BUILD_TIME :&str = "2020-08-16 13:48:52";
pub const COMMIT_DATE :&str = "2020-08-16 13:12:52";
pub const COMMIT_EMAIL :&str = "xxx@gmail.com";
pub const PROJECT_NAME :&str = "shadow-rs";
pub const RUST_CHANNEL :&str = "stable-x86_64-apple-darwin (default)";
pub const BRANCH :&str = "master";
pub const CARGO_LOCK :&str = r#"

Quick Start

step 1

In your cargo.toml packgae with package add with below config

[package]
build = "build.rs"

[dependencies]
shadow-rs = "0.4"

[build-dependencies]
shadow-rs = "0.4"

step 2

In your project add file build.rs,then add with below config

This example is not tested
fn main() -> shadow_rs::SdResult<()> {
   shadow_rs::Shadow::new()
}

step 3

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 The shadow!(build) with build config,add Rust build mod in your project. You can also replace it(build) with other name.

This example is not tested
#[macro_use]
extern crate shadow_rs;

shadow!(build);

step 4

Then you can use const that's shadow build it(main.rs).

The build mod just we use shadow!(build) generated.

This example is not tested
fn main(){
   println!("{}",build::BRANCH); //master
   println!("{}",build::SHORT_COMMIT);//8405e28e
   println!("{}",build::COMMIT_HASH);//8405e28e64080a09525a6cf1b07c22fcaf71a5c5
   println!("{}",build::COMMIT_DATE);//2020-08-16T06:22:24+00:00
   println!("{}",build::COMMIT_AUTHOR);//baoyachi
   println!("{}",build::COMMIT_EMAIL);//xxx@gmail.com

   println!("{}",build::BUILD_OS);//macos-x86_64
   println!("{}",build::RUST_VERSION);//rustc 1.45.0 (5c1f21c3b 2020-07-13)
   println!("{}",build::RUST_CHANNEL);//stable-x86_64-apple-darwin (default)
   println!("{}",build::CARGO_VERSION);//cargo 1.45.0 (744bd1fbb 2020-06-15)
   println!("{}",build::PKG_VERSION);//0.3.13
   println!("{}",build::CARGO_TREE); //like command:cargo tree

   println!("{}",build::PROJECT_NAME);//shadow-rs
   println!("{}",build::BUILD_TIME);//2020-08-16 14:50:25
   println!("{}",build::BUILD_RUST_CHANNEL);//debug
}

Clap example

And you can also use const with clap.
