JetBrains Fleet 1.36 Help

Coding assistance in Rust

In Smart Mode, JetBrains Fleet provides coding assistance features for your Rust projects. They help you avoid mistakes and write code in an efficient manner.

Code completion

As you type, JetBrains Fleet suggests completion options. The suggestions are based on a number of factors, such as the available code intelligence services, project model, surrounding code, and the visibility of symbols.

Code completion popup

Completion suggestions will appear automatically as you type, but you can also invoke them explicitly by pressing ⌃ Space.

When you use code completion over existing code items, you can either insert the selected completion suggestion before the existing item by pressing Enter or replace the existing identifier with the selected suggestion by pressing Tab.

Code actions

JetBrains Fleet constantly analyzes your code and suggests actions that you might want to perform in the current context. The suggested actions range from correcting errors to refactoring the code at the caret.

A popup with code actions

To see, which actions are available at the caret, press ⌥ ⏎. After you have selected the required action, you can apply it right away or preview the result with ⌘ P.
