Trait CPtr

pub trait CPtr {

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.
