Most errors aren’t serious enough to require the program to stop entirely.
Most errors aren’t serious enough to require the program to stop entirely.
Sometimes, when a function fails, it’s for a reason that you can easily interpret and respond to.
For example, if you try to open a file and that operation fails because the file doesn’t exist, you might want to create the file instead of terminating the process.

# Smart Pointers
In Rust, smart pointers are variables that contain an address in memory and reference some other data, but they also have additional metadata and capabilities.
Smart pointers in Rust often own the data they point to, while references only borrow data.

In this way, traits are somewhat similar to Java interfaces and C++ abstract classes.
Some additional common Rust traits include:
- `Clone` (the `clone` method)
- `Display` (which allows formatted display via `{}`)
- `Debug` (which allows formatted display via `{:?}`)
Because traits indicate shared behavior between data types, they are useful when writing generics.

4. If an exercise doesn't make sense to you, feel free to open an issue on GitHub!
(https://github.com/rust-lang/rustlings/issues/new). We look at every issue,
and sometimes, other learners do too so you can help each other out!
5. If you want to use `rust-analyzer` with exercises, which provides features like
autocompletion, run the command `rustlings lsp`.
5. If you want to use `rust-analyzer` with exercises, which provides features like
autocompletion, run the command `rustlings lsp`.
Got all that? Great! To get started, run `rustlings watch` in order to get the first
exercise. Make sure to have your editor open!"#;
