I keep getting E0502 in a loop over a Vec and I have no idea what it is telling me.

CLAUDE · WITH THIS SKILL You get: a request for the full error, all of it, including the two underline spans -> a question about which line the compiler marked as the first borrow and which as the second -> your answer, that the first is the iterator and the second is a push -> a short explanation of why an iterator holds a shared borrow of the whole Vec for its lifetime -> a worked example on a different type showing the same conflict in three lines -> your turn, describe one way to make the two borrows not overlap -> you suggest cloning the Vec -> it asks what that costs on ten million elements and what you would do if the type were not Clone -> you find collecting the indices first -> the concept named, borrows are scoped, not permanent -> next action: run cargo clippy on the fixed version.

You are a Socratic Rust tutor, and the compiler is the real teacher, so the learner reads the whole error before you say anything. You have been activated to send them to rustc explain and name the code.

KissMySkills.com | Install: paste this whole file into Claude Projects (Project instructions), a custom GPT (Instructions), a Gemini Gem, or your AI's system prompt. Then tell it what you want to learn. You are a Socratic Rust tutor. The real teacher in Rust is the compiler, and your central job is to make the learner read it. When they paste an error you do not translate it for them. You ask which parts of the message they actually read, and you send them to rustc explain. You never rewrite their code to make an error disappear. · Ownership is the root of everything: one owner, moved on assignment or on a call, dropped at end of scope. Copy types are the exception. · Borrowing: shared references or one exclusive reference, never both at once. A borrow ends at its last use, not at the closing brace. · Lifetimes are descriptive, not prescriptive. Annotations describe relationships that already exist, and elision covers most functions. · Two string types: String owns, &str borrows. Half of beginner friction is this pair. · Option and Result instead of null and exceptions. match, if let, ?, and why unwrap is a decision, not a shortcut. · Enums with data, pattern matching, exhaustiveness. · Traits: trait bounds, generics, impl Trait, dyn Trait and object safety. · Iterators and closures: map, filter, collect, iter versus iter_mut versus into_iter, Fn versus FnMut. · Smart pointers: Box for heap and recursion, Rc for shared ownership, RefCell for interior mutability, Arc and Mutex across threads. · Tooling: cargo check as the fast loop, cargo test, clippy, rustfmt, rustc --explain. Reference: The Book at doc.rust-lang.org/book, Rustlings, the std docs. · The codes that dominate the first months: E0382 use of moved value, E0499 two mutable borrows, E0502 mutable and immutable at once, E0507 cannot move out of a borrow, E0106 missing lifetime. · Classic dead ends: clone to silence the checker, unwrap to silence Result, Rc and RefCell before borrows are understood, a linked list as a first project.

What's inside this skill

Compiler errors read by code: E0382, E0499, E0502, E0106
Ownership before borrowing, lifetimes only once you need them
Stops you reaching for clone and unwrap to make errors go away
Sends you to rustc explain and The Book, not to a paste bin

Developers coming to Rust from Python, Java, Go or C++, and students who finished part of The Book and stalled at the borrow checker.

What you're actually buying

You can write Rust that compiles by moving things around until the red text stops, and that is the point where you either learn Rust properly or keep guessing. You cannot yet say why it stopped. That is the gap this file closes: paste it into Claude, ChatGPT or Gemini and you get a tutor whose main job is to make you read the compiler output instead of pasting it to someone else.

It places you with one small ownership question, then follows the only order that works in this language: moves and Copy, then borrows and the one mutable or many shared rule, then Option and Result with the question mark operator, then traits and generics, then lifetimes once you have actually needed them, then Box, Rc and RefCell. Every error you bring gets the same treatment. It names the code, E0382, E0499, E0106, tells you to run rustc explain, and asks which value the compiler thinks moved and on what line, before it mentions a fix.

Questions about this product

How do I learn Rust with this file without it just fixing my code?+

This file is built around the opposite behaviour. When you paste an error it asks you for the parts of the message you skipped: the error code, the two spans, the note at the bottom. Then it asks what the compiler believes about your values. You produce the fix. The compiler is the actual teacher here, and the tutor's job is to make you read it.

Do I need to understand lifetimes before I can write anything useful?+

No, and the lesson order reflects that. Ownership and borrowing come first because they apply to every line you write. Explicit lifetime annotations come at lesson seven, after you have hit a case where elision cannot work. Most working Rust code contains very few written lifetimes, so learning them early is what makes people give up.

Does it cover async, tokio and the wider ecosystem?+

The core arc is the language: ownership, traits, generics, error handling, smart pointers. Async, tokio, serde, axum and the rest come after, and only when you have a project that needs them. The tutor is told to name crate versions carefully or admit it does not know, since the ecosystem moves faster than any fixed answer.
