# Entry-Point Runtime — Rust
## Signals to gather
- ELF binaries with DWARF producer strings containing `rustc`.
- Symbols prefixed with `_ZN` (mangled Rust) or section `.rustc`.
- Presence of `panic=abort` strings, `Rust` metadata, or Cargo artefacts (`Cargo.toml`, `Cargo.lock`).
- Statically linked (no `.dynamic` entries) in many cases, or musl loader (`/lib/ld-musl-x86_64.so.1`).
- Environment such as `RUST_LOG`, `RUST_BACKTRACE`.
## Implementation notes
- Parse DWARF `.debug_info` when available; short-circuit by scanning `.comment` sections for `rustc`.
- Distinguish from Go by the absence of `.note.go.buildid`.
- When Cargo artefacts exist, include target name and profile in evidence.
- For binaries built with `--target x86_64-pc-windows-gnu`, treat them under the same detector (PE + Rust markers).
## Evidence & scoring
- Reward DWARF producer strings, Cargo files, and Rust-specific env vars.
- Penalise when only generic static binary traits are present (may defer to C/C++).
- Mention musl vs glibc loader differences for observability.
## Edge cases
- Rust compiled to WebAssembly or run inside Wasmtime falls outside this detector; leave as `Other`.
- Stripped binaries without DWARF or comments may be indistinguishable from C—fall back to C/C++ and add note.
- Supervisors launching multiple Rust binaries handled upstream.
