Modules

• slice_to_cstr 🔒 riot_module_vfs

Traits

• PointerToCStr 🔒
  Trait that eases conversions from a char pointer (no matter the signedness, they are used inconsistently in RIOT) to a CStr. The result is often used with ?.to_str().ok()?.
• ReturnTypeExtractor
  Generalization of the Never type extracting workaround from https://github.com/rust-lang/rust/issues/43301#issuecomment-912390203 – also useful to extract return types of functions that (in what is compatible behavior in C) change their return types.
