Because Rust is a systems programming language, the only thing you need is a good text editor (but not a word proecessor) for writing the source code, and everything else can be done using commands in a terminal session. However, some developers appreciate the functionalities offered by more fully-fledged text editors specific for programming or Integrated Development Environments (IDEs). Rust has a lot of possibilities in this regard. Most Rust developers work with Vim or Emacs, but Rust plugins exist for a host of text editors, like Atom, Brackets, BBEdit, Emacs, Geany, gedit, Kate, TextMate, Textadept, Vim, NEdit, Notepad++, Sublime Text, and Visual Studio Code. Also, some IDEs, such as Eclipse (RustDT), Netbeans (rust-netbeans), IntelliJ, and Visual Studio, provide plugins for Rust; see the updated overview at https://github.com/rust-unofficial/awesome-rust#ides.

These come with a varying range of features, such as syntax highlighting, code formatting, code completion, linting, debugging, Cargo project support, and so on.

The plugins for the popular Sublime Text editor (http://www.sublimetext.com/3) are particularly pleasant to work with and don't get in your way. After having installed Sublime Text (you might want to get a registered version if you start using it regularly), also install the Package Control package (for instructions on how to do that visit https://packagecontrol.io/installation).

Then, to install the Sublime Text Rust plugin, open the command palette in Sublime Text (Ctrl+Shift+P on Windows or cmd+Shift+P on OS X) and select Package Control | Install Package and then select RustEnhanced from the list.

Sublime Text is a very complete text editor, including color schemes. The Rust plugin provides syntax highlighting and auto-completion; type one or more letters, choose an option from the list that appears with an arrow key and then press Tab to insert the code snippet, or simply select a list option through a mouse click.

When working with Rust code, select Tools | Build System and RustEnhanced.

Then, you can run and compile a source file with Ctrl+B. Warnings or errors appear in the lower panel; if everything is OK the output of the program appears together with a message like the following:

    [Finished in 0.6s]

If you want to do the two steps separately, do Ctrl+Shift+B. A pop-up menu appears, click on RustEnhanced if you only want to compile, click on RustEnhanced | Run if you want to execute the program. A SublimeLinter plugin exists that provides an interface to rustc, called SublimeLinter-contrib-rustc. It does additional checks on your code for stylistic or programming errors. You can install it as indicated above through Package Control and then use it from the menu Tools | SublimeLinter (for more details consult https://github.com/oschwald/SublimeLinter-contrib-rustc).

There are also plugins for IDEs like:

• For Eclipse, called RustDT: https://github.com/RustDT/RustDT
• For IntelliJ called intellij-rust: https://github.com/intellij-rust/intellij-rust
• For NetBeans called rust-netbeans: https://github.com/drrb/rust-netbeans
• For Visual Studio called VisualRust: https://github.com/PistonDevelopers/VisualRust

You can test out Rust code even without local installation with the Rust Playground at http://play.rust-lang.org/, which allows you to edit or paste your code and evaluate it.

The interactive shell rusti or Read-Evaluate-Print-Loop (REPL) is in development for Rust, which is common for dynamic languages, but remarkable for a statically compiled language. You can find it at https://github.com/murarth/rusti.

An online environment that combines both is repl.it. Refer the following link for more details https://repl.it/languages/rust.
