Code Audit #10 of 17

Apply the code quality criteria from CONTRIBUTING.md "What Good Code Looks Like":

Files to audit:

• crates/compiler/src/codegen/ffi_wrappers.rs
• crates/compiler/src/codegen/platform.rs
• crates/compiler/src/ffi.rs

Checklist:

• Structure: First 50 lines tell you what file does, logical function ordering
• Naming: Functions say what they do, variables reveal intent
• No Surprises: All public functions used, no commented-out code, no stale TODOs
• Single Responsibility: Each function does one thing, consistent error handling
• Tests: Complex logic has tests, edge cases covered

Audit Summary

Reviewed against CONTRIBUTING.md "What Good Code Looks Like" criteria.

Files Reviewed

ffi_wrappers.rs (~411 lines)

• Structure: Clean separation of concerns - wrapper generation for different return types
• Naming: Clear function names like codegen_ffi_wrapper, codegen_ffi_wrapper_returning_void
• No Surprises: Well-documented parameter handling (by_ref, C strings, memory ownership)
• Single Responsibility: Each function handles one wrapper pattern
• Tests: FFI wrappers tested via integration tests

platform.rs (~67 lines)

• Structure: Simple, focused module for platform-specific object file format detection
• Naming: Clear ObjectFormat enum and default_object_format() function
• No Surprises: Straightforward target triple parsing
• Single Responsibility: Only platform detection

ffi.rs (~698 lines)

• Structure: Excellent - clear sections for parsing, validation, types
• Naming: Descriptive types (FfiManifest, FfiFunction, FfiTypeRef)
• No Surprises: Security checks for linker flag injection, thorough validation
• Single Responsibility: FFI manifest parsing and validation
• Tests: Comprehensive test suite (20+ tests covering parsing, validation, edge cases)

Findings

• No stale TODOs or FIXMEs
• No #[allow(dead_code)] annotations
