📝 Walkthrough
Walkthrough
Updates function pointer casting patterns across multiple modules to use explicit intermediate pointer casts (*const ()) before final type conversion. Changes affect signal handler registration, hash sentinel detection, memory function address computation, and method descriptor comparison.
Changes
| Cohort / File(s) |
Summary |
Signal Handler Casting
crates/stdlib/src/faulthandler.rs, crates/vm/src/stdlib/signal.rs |
Function pointers cast to libc::sighandler_t now use intermediate *const () cast instead of direct type conversion for faulthandler fatal/user signal handlers and signal module handler installation |
Pointer Address Computation
crates/vm/src/stdlib/ctypes.rs |
Function addresses for _memmove_addr and _memset_addr computed via *const () intermediate cast before usize conversion instead of direct cast |
Type-Unsafe Pointer Comparisons
crates/vm/src/class.rs, crates/vm/src/vm/method.rs |
Hash sentinel detection and method descriptor comparison now use intermediate *const () pointer cast for safe type-level comparisons |

- Faulthandler #6406: Modifies signal-handling code in faulthandler.rs; this PR adjusts function-pointer cast patterns for the same handler-wiring code paths.
- Faulthandler #6400: Overlaps with faulthandler.rs changes; both PRs modify signal-handler installation and casting logic.
- __hash__ to slot_wrapper #6480: Related through class.rs
__hash__ slot handling; this PR refines the pointer cast used for hash_not_implemented sentinel detection.

Poem
🐰 Through pointers cast with careful care,
Each function finds its destined lair,
No direct leaps, just steps between,
The safest path our code has seen! ✨
