build_id2: A maintained way to uniquely represent the build of the current binary

The build_id2 crate is a maintained and updated fork of build_id. With it, you can obtain a Uuid uniquely representing the build of the current binary.

This is intended to be used to check that different processes are indeed invocations of identically laid out binaries.

As such:

  • It is guaranteed to be identical within multiple invocations of the same binary.
  • It is guaranteed to be different across binaries with different code or data segments or layout.
  • Equality is unspecified if the binaries have identical code and data segments and layout but differ immaterially (e.g. if a timestamp is included in the binary at compile time).

Usage

Add the following to your Cargo.toml:

[dependencies]
build_id2 = "0.16.1"

Then, you can use the get function to get the build id:

# let remote_build_id = build_id2::get();
let local_build_id = build_id2::get();
if local_build_id == remote_build_id {
    println!("We're running the same binary as remote!");
} else {
    println!("We're running a different binary to remote");
}

Contributing

For bugs, feel free to open issues or contact us directly. Thank you for your support. <3

Even though we will gladly assist you in finishing up your PR, try to

  • keep all the crates compiling with stable rust (hide the eventual non-stable code under cfgs.)
  • run cargo nightly fmt on your code before pushing
  • check the output of cargo clippy --all or ./clippy.sh
  • run cargo build --no-default-features to check for no_std compatibility (and possibly add #[cfg(feature = "std")]) to hide parts of your code.

Some parts in this list may sound hard, but don't be afraid to open a PR if you cannot fix them by yourself. We will gladly assist.
