Trait PlaceDeref 

pub unsafe trait PlaceDeref<P>
where
    P: Projection + ?Sized,
    P::Target: HasPlace,
    Self: HasPlace<Target = P::Source>,
{
    // Required method
    unsafe fn double_deref(ptr: *mut Self, p: &P) -> *const P::Target;
}

Allows dereferencing a subplace that contains a pointer. The returned pointer will only be used for further place operations.

Required Methods

unsafe fn double_deref(ptr: *mut Self, p: &P) -> *const P::Target

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
