HAL Design Patterns Checklist
  • Naming (crate aligns with Rust naming conventions)
  • Interoperability (crate interacts nicely with other library functionality)
    • [ ] Wrapper types provide a destructor method (C-FREE)
    • [ ] HALs reexport their register access crate (C-REEXPORT-PAC)
    • [ ] Types implement the embedded-hal traits (C-HAL-TRAITS)
  • Predictability (crate enables legible code that acts how it looks)
    • [ ] Constructors are used instead of extension traits (C-CTOR)
  • GPIO Interfaces (GPIO Interfaces follow a common pattern)
    • [ ] Pin types are zero-sized by default (C-ZST-PIN)
    • [ ] Pin types provide methods to erase pin and port (C-ERASED-PIN)
    • [ ] Pin state should be encoded as type parameters (C-PIN-STATE)
