3 A small tool to help you generate version information
4 for packages installed from a git repo
8 Add a `build.rs` file to your repo and list it in `Cargo.toml`
13 List rustc_tools_util as regular AND build dependency.
16 rustc_tools_util = "0.1"
19 rustc_tools_util = "0.1"
22 In `build.rs`, generate the data in your `main()`
26 "cargo:rustc-env=GIT_HASH={}",
27 rustc_tools_util::get_commit_hash().unwrap_or_default()
30 "cargo:rustc-env=COMMIT_DATE={}",
31 rustc_tools_util::get_commit_date().unwrap_or_default()
37 Use the version information in your main.rs
39 use rustc_tools_util::*;
42 let version_info = rustc_tools_util::get_version_info!();
43 println!("{}", version_info);
46 This gives the following output in clippy:
47 `clippy 0.0.212 (a416c5e 2018-12-14)`
