built provides a crate with information from the time it was built.

built is used as a build-time dependency to collect various information about the build-environment, serialize this information into Rust-code and provide that to the crate. The information collected by built include:

• Various metadata like version, authors, homepage etc. as set by Cargo.toml
• The tag or commit id if the crate was being compiled from within a Git repository.
• The values of CARGO_CFG_* build script environment variables, like CARGO_CFG_TARGET_OS and CARGO_CFG_TARGET_ARCH.
• The features the crate was compiled with.
• The various dependencies, dependencies of dependencies and their versions Cargo ultimately chose to compile.
• The presence of a CI-platform like Github Actions, Travis CI and AppVeyor.
• The compiler and it's version; the documentation-generator and it's version.

See the example or the docs for more information.

// In build.rs

fn main() {
    built::write_built_file().expect("Failed to acquire build-time information")
}

// In lib.rs or main.rs

// Include the generated-file as a separate module
pub mod built_info {
    include!(concat!(env!("OUT_DIR"), "/built.rs"));
}

println!(
    "This is version {}, built for {} by {}.",
    built_info::PKG_VERSION,
    built_info::TARGET,
    built_info::RUSTC_VERSION
);

match built_info::CI_PLATFORM {
    None => print!("It seems I've not been built on a continuous integration platform,"),
    Some(ci) => print!("I've been built on CI-platform {},", ci),
}

if built::util::detect_ci().is_some() {
    println!(" but I'm currently executing on one!");
} else {
    println!(" and I'm currently not executing on one!");

This is version 0.1.0, built for x86_64-unknown-linux-gnu by rustc 1.77.2 (25ef9e3d8 2024-04-09).

I was built from git 0.7.2-3-g4014a2e, commit 4014a2eb4e8575bec9a1f17ae7b92d8956ecd1fd, short_commit 4014a2e; the working directory was "clean". The branch was refs/heads/master.

I was built for a x86_64-CPU, which is a little-endian architecture. I was compiled to run on linux (a unix-breed) and my runtime should be gnu.

It seems I've not been built on a continuous integration platform, and I'm currently not executing on one!
