THIS IS A FORK OF https://github.com/alecmocatta/build_id!
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).
rust
let local_build_uuid = build_uuid::get();
if local_build_uuid == remote_build_uuid {
println!("We're running the same binary as remote!");
} else {
println!("We're running a different binary to remote");
}
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.
