RustRover 2023.3 Help

Indexing

Indexing in RustRover is responsible for the core features of the IDE: code completion, inspections, finding usages, navigation, syntax highlighting, and refactorings.

It starts when you open your project, switch between branches, after you load or unload plugins, and after large external file updates. For example, this can happen if multiple files in your project are created or generated after you build your project.

Indexing is in progress

Indexing examines the code of your project to create a virtual map of types, methods, objects, and other code elements that make up your application. This is necessary to provide the coding assistance functionality, search, and navigation instantaneously. After indexing, the IDE is aware of your code. That is why actions like finding usages or smart completion are performed immediately.

While indexing is in progress, the above-mentioned coding assistance features are unavailable or partially available. Nevertheless, you can still work with the IDE: you can type code, work with VCS features, configure settings, and perform other code-unrelated actions.

Decreasing time for indexing

The amount of time required for indexing varies depending on your project: the more complex your project is, the more files it comprises, the more time it takes to index it. You can decrease the indexing time by excluding files and folders and by unloading modules.

Exclude files and folders

Marking dynamically generated files as excluded can speed up the indexing and overall IDE performance. For example, RustRover automatically excludes the target directory that stores build output. Excluded files remain a part of the project, but are ignored by code completion, navigation, indexing, and inspections.

Exclude files from indexing

  1. Right-click a file in the Project tool window (Alt+1).

  2. Select Override File Type | Plain text.

    Plain text files are marked with the Plain text icon.

Exclude folders from indexing

  1. Right-click a folder in the Project tool window (Alt+1).

  2. Select Mark Directory as | Excluded.

    Excluded folders are marked with the the Excluded root icon icon.

You can also Exclude files and folders by name patterns.
