Is there any way of doing tagged references in safe Rust? I've been looking at tagged pointers (the crate https://docs.rs/tagged-pointer/latest/tagged_pointer/ looks excellent) but it gives you back a raw pointer. I'm not sure if you can create a safe wrapper for references using tagged pointers.
tagged_pointer - Rust
This crate provides an implementation of tagged pointers: a space-efficient representation of a pointer and integer tag. In particular, both `TaggedPtr` and `Option<TaggedPtr>` are the size of a pointer despite containing both a pointer and tag.

Some excellent safety improvements in C++26: hardening the standard library against out-of-bounds bugs, and a safer semantics for uninitialised local variables:

Excellent series on Self, both the programming model and the tool chain. I love how opening an inspector on a value (e.g. nil) then shows a link to all occurrences of the value in other open inspectors!

I bring you a message about a language that has been at the birth of many others, but almost no one knows it. A rumor of a graphical environment offering options like no other, but almost no one using it. I also bring information about a virtual machine supporting reflection almost to infinity, reaching almost half of the operating power of C in numerical calculations in its time, yet today forgotten.
