LabRust
Recover the Parcel Tracker
Repair a Rust parcel tracker that uses a String after it moves, preserving its returned ownership without cloning.
ChallengeRust
Ownership, Scope, and Moves
Learn Rust ownership by comparing copied integers with moved String data, reading an intentional E0382 diagnostic, and returning ownership from a function.
LabRust
Update a Guest List Safely
Repair a guest-list program so one function borrows for inspection and another borrows for controlled mutation.
ChallengeRust
Borrow Data with References
Learn to inspect and update owned Rust data with shared and mutable references while the caller keeps ownership.
LabRust
Extract Command Keywords
Complete a borrowed string-slice helper that extracts the first keyword from empty, single-word, and multi-word commands.
