========================================

shadow-rs build tool

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 example_shadow for a simple demonstration of how shadow-rs might be used to provide build-time information at run-time.
Check out the exampleshadowhook for a simple demonstration of how shadow-rs might be used to provide build-time information at run-time,and add custom hook.
built in function:examples.

Setup Guide

1) Modify `Cargo.toml` fields

Modify your Cargo.toml like so:

```TOML [package] build = "build.rs"

[dependencies] shadow-rs = "0.6"

[build-dependencies] shadow-rs = "0.6" ```

2) Create `build.rs` file

Now in the root of your project (same directory as Cargo.toml) add a file build.rs: * with add custom const or fn see:exampleshadowhook

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

3) Integrate shadow

In your rust file (e.g. *.rs):

```rust use shadow_rs::shadow;

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.

```rust fn main() {

//shadow-rs built in function  
println!("{}", shadow_rs::is_debug());      // check if this is a debug build
println!("{}", shadow_rs::branch());        // get current project git branch. e.g.'master'
println!("{}", shadow_rs::tag());           // get current project git head tag. e.g.'v1.5.3'

//shadow-rs built in const   
println!("{}", build::version());           // the version (description binary detail information)
println!("{}", build::clap_version());      // usually used by clap crates version() (description binary detail information)
println!("{}", build::PKG_VERSION);         // current package version. e.g. '1.3.15-beta2'

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_TIME_2822);     // time when start build occurred by rfc2822, e.g. 'Thu, 24 Jun 2021 21:33:59 +0800'
println!("{}", build::BUILD_TIME_3339);     // time when start build occurred by rfc3339, e.g. '2021-06-24T21:33:59.972494+08:00'
println!("{}", build::BUILD_RUST_CHANNEL);  // e.g. 'debug'

} ```

Clap Example

And you can also use shadow-rs with clap.

Support const,function in table

shadow-rs built in function.

how to use 👉 : examples

| function | desc | | ------ | ------ | | is_debug() | check if this is a debug build.e.g.'true/false' | | branch() | get current project branch.e.g.'master/develop' | | tag() | get current project tag.e.g.'v1.3.5' |

shadow-rs support build const,function.
