Function static_metadata

pub const fn static_metadata<S, T: ?Sized>() -> <T as Pointee>::Metadata
where
    S: Unsize<T>,

Available on crate feature ptr_metadata only.

This metadata is usually a pointer to vtable of T implementation for S, but can be something else and the value is considered internal to the compiler.
