[Docs](https://docs.rs/build_id/0.2.1)

Obtain a [`Uuid`](https://docs.rs/uuid/0.8/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).

## Examples

```rust

let local_build_id = build_id::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");

}

```

## Note

This looks first for linker-inserted build ID / binary UUIDs (i.e.

`.note.gnu.build-id` on Linux; `LC_UUID` in Mach-O; etc), falling back to

hashing the whole binary.
