pub fn current_executable_build_id() -> Option<Vec<u8>>Expand description
Return the GNU build ID of the running executable without reading the executable from disk.
The dynamic loader has already mapped the main image’s PT_NOTE segment,
so callers that only need an image-generation identity do not need to hash
a potentially large unoptimized binary. None preserves a clean fallback
for binaries linked without a GNU build ID.
