Rustfmt can be utilized from rust-analyzer which is provided by ide-rust.
apm install ide-rust
Once installed a file is formatted with ctrl-shift-c or cmd-shift-c, also available in context menu.
Another way is to install Beautify, you
can do this by running apm install atom-beautify.
There are 2 settings that need to be configured in the atom beautifier configuration.
-
Install rustfmt as per the readme.
-
Open the atom beautifier settings
Go to Edit->Preferences. Click the packages on the left side and click on setting for atom-beautifier
-
Set rustfmt as the beautifier
Find the setting labeled Language Config - Rust - Default Beautifier and make sure it is set to rustfmt as shown below. You can also set the beautifier to auto format on save here.
-
Set the path to your rustfmt location
Find the setting labeled Rust - Rustfmt Path. This setting is towards the bottom and you will need to scroll a bit. Set it to the path for your rustfmt executable.
