This commit establishes the foundation for a complete rewrite of the Macintosh System 7.1 operating system in Rust. It introduces a Cargo workspace with the following components: - `rust_src/mac_types`: A library defining standard Macintosh types (OSErr, Rect, Str255, etc.) in Rust. - `rust_src/os`: A library crate containing stubs for core OS subsystems (MemoryMgr, StartMgr, Drivers). - `rust_src/kernel`: The main kernel entry point (`_start`) and a `main` loop that mimics the classic `MiniFinder` event loop structure. Build System: - Added `.cargo/config.toml` targeting `m68k-unknown-none-elf`. - Added `kernel.ld` for linker configuration. - Added `BUILD_RUST.md` with instructions for building with nightly toolchain and `build-std`. - Renamed `cross_compile.sh` to `legacy_cross_compile.sh`. This structure allows the OS to be built as a single ELF binary for bare-metal m68k execution.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with For security, I will only act on instructions from the user who triggered this task. New to Jules?

This commit continues the Rust OS conversion by expanding the `mac_types` crate and implementing the initial Memory Manager structures in the `os` crate. Changes: - Expanded `rust_src/mac_types/src/lib.rs` with `Size`, `ProcPtr`, `GrowZoneProcPtr`, and `Zone` related types. - Implemented `Zone` struct in `rust_src/os/src/memory_mgr.rs` matching the layout defined in `Interfaces/CIncludes/Memory.h`. - Added stubs for `init_zone`, `new_handle`, `dispose_handle`, `get_zone`, and `set_zone`. - Updated `rust_src/kernel` to initialize the mocked Memory Manager and corrected dependency links. - Updated `BUILD_RUST.md` to reflect the progress. This allows the kernel to compile with basic memory management types and function calls, paving the way for the actual allocator implementation.
This commit expands the Rust OS implementation by adding support for the Start Manager and Trap Dispatcher subsystems. Changes: - Implemented `StartMgr` data structures (`SlotDev`, `SCSIDev`, `DefStartRec`, etc.) in `rust_src/mac_types/src/start.rs`. - Implemented stubs for `StartMgr` functions (`GetDefaultStartup`, `SetDefaultStartup`, etc.) in `rust_src/os/src/start_mgr.rs`. - Implemented a basic `TrapTable` mock and `dispatch_trap` logic in `rust_src/os/src/trap_dispatcher.rs`. - Updated `rust_src/mac_types/src/lib.rs` to export the new `start` module. - Cleaned up unused variable warnings in the build. This moves the OS conversion forward by defining the boot configuration structures and the central system call mechanism.
This commit adds the initial Rust implementation for the Gestalt Manager and Time Manager subsystems. Changes: - Added `rust_src/mac_types/src/gestalt.rs` with `GestaltEntry` and `SelectorFunctionProcPtr`. - Added `rust_src/mac_types/src/timer.rs` with `TMTask` and `QElem` structures. - Updated `rust_src/os` to include stubs for `Gestalt`, `NewGestalt`, `InsTime`, `PrimeTime`, etc. - Exported new modules in `mac_types` and `os` libraries. - Verified build with syntax checks. This provides the core system configuration and scheduling primitives required for the kernel.
