Exploring Self-Borrowing Patterns in Rust's Type System
By

A baker's-dozen of insight crammed into one ring.
Summary
This article explores advanced Rust programming concepts, specifically addressing the common belief that self-borrowing (passing an object and a reference to that object simultaneously) is impossible in Rust. The author argues this is not an inherent limitation of borrow checking but rather a current implementation constraint, and discusses theoretical approaches and patterns that could make self-borrows safe in Rust's type system.

· 3 pulledOne of the first things any Rust programmer learns is that you can't pass an object and a reference to that object around at the same time.
It's so well-known that most people treat it like an axiom, not just a limitation of Rust as it currently exists, but an inherent limitation of borrow checking in general.
However, that's not the case.
