Trait vizia_core::vg::wrapper::RefWrapper
pub unsafe trait RefWrapper<N> {
// Required methods

fn inner_mut(&mut self) -> &mut N;
}Expand description
A trait that supports the conversion from a C/C++ reference into its Rust wrapper and back.
The wrapped value can be accessed through the functions inner and inner_mut.
This trait is implemented for all wrapper types that wrap C/C++ references.
§Safety
The native type N should be treated as opaque, because its definition may change
without adhering to semantic versioning and depends on what the tool bindgen is able to generate.
Converting from a Rust wrapper to a wrapped value may lose the automatic ability to free associated memory.
Required Methods§
fn wrap_ref(native: &N) -> &Self
fn wrap_mut(native: &mut N) -> &mut Self
fn inner(&self) -> &N
fn inner_mut(&mut self) -> &mut N
Object Safety§
This trait is not object safe.
