shadow-rs:: build-time information stored in your rust project.(binary,lib,cdylib,dylib)

shadow-rs allows you to recall properties of the build process and environment at runtime, including:

• Cargo.toml project version
• Dependency information
• The Git commit that produced the build artifact (binary)
• What version of the rust toolchain was used in compilation
• The build variant, e.g. debug or release
• (And more)

You can use this tool to check in production exactly where a binary came from and how it was built.

Full Examples

• Check out the shadow_example for a simple demonstration of how shadow-rs might be used to provide build-time information at run-time.
• built in method:examples.

Setup Guide

1) Modify Cargo.toml fields

Modify your Cargo.toml like so:

[package]
build = "build.rs"

[dependencies]
shadow-rs = "0.5"

[build-dependencies]
shadow-rs = "0.5"

2) Create build.rs file

Now in the root of your project (same directory as Cargo.toml) add a file build.rs:

fn main() -> shadow_rs::SdResult<()> {
    shadow_rs::new()
}

3) Integrate Shadow

In your root rust file (e.g. main.rs, or lib.rs):

#[macro_use]
extern crate shadow_rs;

shadow!(build);

Notice that the shadow! macro is provided the identifier build. You can now use this identifier to access build-time information.

4) Done. Use Shadow.

fn main() {

    //shadow-rs built in method  
    println!("{}", shadow_rs::is_debug());      // check if this is a debug build
    println!("{}", shadow_rs::branch());        // get current project git branch. e.g.'master'

    //shadow-rs built in const   
    println!("{}", build::version());           // the version (description binary detail information)
    println!("{}", build::PKG_VERSION);         // current package version. e.g. '1.3.15-beta2'  
    println!("{}", build::PKG_VERSION_MAJOR);   //current package major version. e.g. '1'  
    println!("{}", build::PKG_VERSION_MINOR);   //current package minor version. e.g. '3'  
    println!("{}", build::PKG_VERSION_PATCH);   //current package minor version. e.g. '15'  
    println!("{}", build::PKG_VERSION_PRE);   //current package minor version. e.g. 'beta2'  
    println!("{}", build::BRANCH);              // the branch, e.g. 'master'
    println!("{}", build::TAG);                 // the tag, e.g. 'v1.0.0'
    println!("{}", build::SHORT_COMMIT);        // short commit hash, e.g. '8405e28e'
    println!("{}", build::COMMIT_HASH);         // full commit hash, e.g. '8405e28e64080a09525a6cf1b07c22fcaf71a5c5'
    println!("{}", build::COMMIT_DATE);         // commit date, e.g. '2020-08-16 11:52:47'
    println!("{}", build::COMMIT_AUTHOR);       // commit author, e.g. 'baoyachi'
    println!("{}", build::COMMIT_EMAIL);        // commit email, e.g. 'example@gmail.com'

    println!("{}", build::BUILD_OS);            // the OS that built the binary, e.g. 'macos-x86_64'
    println!("{}", build::RUST_VERSION);        // rustc version e.g. 'rustc 1.45.0 (5c1f21c3b 2020-07-13)'
    println!("{}", build::RUST_CHANNEL);        // rust toolchain e.g. 'stable-x86_64-apple-darwin (default)'
    println!("{}", build::CARGO_VERSION);       // cargo version e.g. 'cargo 1.45.0 (744bd1fbb 2020-06-15)'
    println!("{}", build::CARGO_TREE);          // e.g. the output of '$ cargo tree'

    println!("{}", build::PROJECT_NAME);        // your project name, e.g. 'shadow-rs'
    println!("{}", build::BUILD_TIME);          // time when start build occurred, e.g. '2020-08-16 14:50:25'
    println!("{}", build::BUILD_RUST_CHANNEL);  // e.g. 'debug'
}
