Rustlings 6.3.0

Added

• Add the following exercise lints:
  • forbid(unsafe_code): You shouldn't write unsafe code in Rustlings.
  • forbid(unstable_features): You don't need unstable features in Rustlings and shouldn't rely on them while learning Rust.
  • forbid(todo): You forgot a todo!().
  • forbid(empty_loop): This can only happen by mistake in Rustlings.
  • deny(infinite_loop): No infinite loops are needed in Rustlings.
  • deny(mem_forget): You shouldn't leak memory while still learning Rust.
• Show a link to every exercise file in the list.
• Add scroll padding in the list.
• Break the help footer of the list into two lines when the terminal width isn't big enough.
• Enable scrolling with the mouse in the list.
• dev check: Show the progress of checks.
• dev check: Check that the length of all exercise names is lower than 32.
• dev check: Check if exercise contains no tests and isn't marked with test = false.

Changed

• The compilation time when installing Rustlings is reduced.
• Pressing c in the list for "continue on" now quits the list after setting the selected exercise as the current one.
• Better highlighting of the solution file after an exercise is done.
• Don't show the output of successful tests anymore. Instead, show the pretty output for tests.
• Be explicit about q only quitting the list and not the whole program in the list.
• Be explicit about r only resetting one exercise (the selected one) in the list.
• Ignore the standard output of git init.
• threads3: Remove the queue length and improve tests.
• errors4: Use match instead of a comparison chain in the solution.
• functions3: Only take u8 to avoid using a too high number of iterations by mistake.
• dev check: Always check with strict Clippy (warnings to errors) when checking the solutions.

Fixed

• Fix the error on some systems about too many open files during the final check of all exercises.
• Fix the list when the terminal height is too low.
• Restore the terminal after an error in the list.

Rustlings 6.2.0

Added

• Show a message before checking and running an exercise. This gives the user instant feedback and avoids confusion if the checks take too long.
• Show a helpful error message when trying to install Rustlings with a Rust version lower than the minimum one that Rustlings supports.
• Add a README.md file to the solutions/ directory.
• Allow initializing Rustlings in a Cargo workspace.
• dev check: Check that all solutions are formatted with rustfmt.

Changed

• Remove the state file and the solutions directory from the generated .gitignore file.
• Run the final check of all exercises in parallel.
• Small exercise improvements.
