#[repr(transparent)]
pub struct Ref<A, T: ?Sized> { pub val: A, /* private fields */ }
Expand description

A wrapper around a base type A to indicate that the value is pointing to a value of type T.

This is not a strict type safety barrier; it is possible to convert a Ref to and from its raw version. However this can help in API documentation, as well as to assist type inference in functions like LocalMap::get.

Fields

val: A

The underlying storage or “raw” value.
