cargo-asm is a cargo subcommand that displays the assembly or LLVM IR generated for Rust source code. It supports querying functions and methods by path, annotating assembly with Rust source, and outputting Intel/AT&T syntax or a JSON AST.

Use cases

• view the assembly generated for a Rust function
• inspect LLVM IR emitted by rustc for a method
• check how the compiler optimizes a hot function
• compare assembly across Rust nightly and stable
• dump assembly as JSON for further processing
• see Rust source interleaved with generated assembly

When to choose

• you need to inspect compiler output for performance tuning of Rust code
• you want a quick cargo-integrated way to view asm or LLVM IR for specific functions
• you work across x86, ARM, MIPS, PowerPC, or SPARC targets

When to avoid

• you need a general-purpose disassembler for binaries rather than compiler output
• you need a debugger or profiler instead of static code inspection
• you need actively developed tooling with frequent updates
