Working with TOML files
In Rust, the TOML format is used to write package manifests – Cargo.toml files. For more information about the TOML format, check out the Cargo book. Below you will find the main features for working with TOML files in RustRover.
Highlighting and code style
The highlighting and code style settings are applied to .toml files automatically. You can adjust the settings in .
Code completion
Code completion works for most manifest keys and Cargo features. You can also autocomplete local dependency paths and navigate to the source via click:
When specifying dependencies from crates.io, you can autocomplete their names and versions:
Navigation
You can navigate across Cargo features and jump to feature declarations from cfg and cfg_attr attributes:
Inspections
The IDE runs a number of inspections to verify Cargo.toml. It checks whether the referenced crates exist and whether their versions are up-to-date. It also detects any cyclic feature dependencies.
Most problems can be fixed in one click: press Alt+Enter to view the options.
Enabling and disabling features
There's a smart UI for enabling/disabling specific features of your workspace right in the Cargo.toml file. It affects name resolution and code insight across the entire project.
View crate documentation
You will see a docs.rs gutter icon next to each extern crate declaration – you can use it to quickly open the crates.io description of the crate in your browser:
