8 Design Patterns

8.1.1 Checklist

• Naming (crate aligns with Rust naming conventions)
  • [ ] The crate is named appropriately (C-CRATE-NAME)
• 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)
