}Expand description
A trait for producing pointers that will always be valid in C (assuming NULL pointer is a valid no-op).
Rust does not guarantee pointers to Zero Sized Types (https://doc.rust-lang.org/nomicon/exotic-sizes.html#zero-sized-types-zsts). In case the type is empty this trait will return a NULL pointer, which should be handled in C.

This trait enables interaction with the FFI layer and even though it is part of the public API
normal users should never need to directly interact with FFI types.
