Questions tagged [rust-obsolete]

Versions of Rust predating 1.0 can have drastically different syntax and semantics. Some questions for these versions no longer apply to a stable version of Rust but are of historical interest.

The Rust programming language evolved drastically before the first stable release. Code written for Rust 0.6 can have very different syntax from code written for Rust 1.0, and sometimes entire concepts or features of the language were added or removed.

This tag is for questions that are not applicable for any stable version of Rust (e.g. 1.0.0 and up).

How do I make my struct fields mutable when accessing through a shared box ptr?

Editor's note: This code is from a version of Rust prior to 1.0 and is not syntactically or semantically valid Rust 1.0 code. So, scoping out shared box pointers as a learning exercise. Purely academic exercise. #[feature(managed_boxes)]; struct…
