}Expand description
Allow conversion to/from raw (winapi) pointer types.
⚠️ Safety ⚠️
Lots of code depends on implicit invariants of this trait for soundness:
- Raw::into_raw and Raw::as_raw have sane implementations.
- If Raw::Raw is a winapi::Interface, it too must be “sane” (correct guid, sound implementation of the COM interface in question, etc.)
- Probably more I’m not thinking of
Associated Types
Required methods
Take ownership from a raw winapi type, panicing if raw is null.
⚠️ Safety ⚠️
rawmust either be null or a sane/valid instance of the type in question.
Panics
- If
rawis null
unsafe fn from_raw_opt(raw: *mut Self::Raw) -> Option<Self>
unsafe fn from_raw_opt(raw: *mut Self::Raw) -> Option<Self>
Take ownership from a raw winapi type, returning None if raw is null.
⚠️ Safety ⚠️
rawmust either be null or a sane/valid instance of the type in question.
