Greetings Rustaceans and welcome here， if you have the following problems:

## Learning Rust
If you are a first-time Rust learner, here are some high quality learning resources :
- [The Book](https://doc.rust-lang.org/book/index.html) for English  speakers
- [Rust语言圣经(The Course)](https://course.rs) for Chinese speakers, it covers nearly all the topics in Rust


## difference to rustlings
[Rustlings](https://github.com/rust-lang/rustlings) only contains small and easy exercises for junior rust devs. There is a big gap between learning Rust and using it in your projects.

Another limit for rustlings is that you have to download rustlings to local machine and compile it first before starting to learn.

## difference to rust by example
[Rust By Example](https://doc.rust-lang.org/stable/rust-by-example/) is an excellent online book for learning Rust，`exercise.rs` has some small advantages in :

- more topics and exercises，specially for the hard part of Rust，e.g string, lifetime, smart pointers, threads and async/.await etc
- difficulty from easy to hard，it will minimize the gap between learning and using in projects
- up-to-date, e.g features which added in Rust 1.59 also have the corresponding exercises in `practice.rs`
- real practices
