staticlib-rename-internal-symbols
When building a staticlib, this option renames all non-exported Rust-internal
symbols by appending a _rs{hash} suffix. This prevents symbol collisions when
multiple Rust static libraries are linked into the same final binary.
This option only renames symbols; it does not change their visibility.
Use -Zstaticlib-hide-internal-symbols in addition if you also want to hide
internal symbols.
Only symbols explicitly exported via #[no_mangle] or #[export_name] are left
unchanged. All other GLOBAL/WEAK symbols (including pub(crate) and pub
items without #[no_mangle]) are renamed.
This option can only be used with --crate-type staticlib. Using it with
other crate types will result in a compilation warning.
Supported on ELF targets (Linux, BSD, etc.) and Apple targets (macOS, iOS, etc.). On unsupported targets (Windows), a warning is emitted and the flag has no effect.
