Prerequisites

Rust Toolset is installed.
For more information, see Installing Rust Toolset.

```
yum install rust-toolset-1.66-rustfmt
```
```
# yum install rust-toolset-1.66-rustfmt
```

Use rustfmt as a standalone tool to format a Rust source file and all its dependencies. As an alternative, use rustfmt with the Cargo build tool. For more information, see Using rustfmt with Cargo.

Prerequisites

An existing Rust project.
For information on how to create a Rust project, see Creating a Rust project.

Procedure

To format a Rust source file using rustfmt as a standalone tool, run the following command:

On Red Hat Enterprise Linux 7:
```
scl enable rust-toolset-1.66 'rustfmt <source-file>'
```
```
$ scl enable rust-toolset-1.66 'rustfmt <source-file>'
```
Copy to Clipboard Toggle word wrap
- Replace <source_file> with the name of your source file.
  Alternatively, you can replace <source_file> with standard input. rustfmt then provides its output in standard output.
On Red Hat Enterprise Linux 8:
```
rustfmt <source-file>
```
```
$ rustfmt <source-file>
```
Copy to Clipboard Toggle word wrap
- Replace <source_file> with the name of your source file.
  Alternatively, you can replace <source_file> with standard input. rustfmt then provides its output in standard output.
On Red Hat Enterprise Linux 9:
```
rustfmt <source-file>
```
```
$ rustfmt <source-file>
```
Copy to Clipboard Toggle word wrap
- Replace <source_file> with the name of your source file.
  Alternatively, you can replace <source_file> with standard input. rustfmt then provides its output in standard output.

Note

By default, rustfmt modifies the affected files without displaying details or creating backups. To display details and create backups, run rustfmt with the --write-mode value.

Procedure

To format all source files in a Cargo code package, run the following command:

On Red Hat Enterprise Linux 7:
```
scl enable rust-toolset-1.66 'cargo fmt'
```
```
$ scl enable rust-toolset-1.66 'cargo fmt'
```
Copy to Clipboard Toggle word wrap
On Red Hat Enterprise Linux 8:
```
cargo fmt
```
```
$ cargo fmt
```
Copy to Clipboard Toggle word wrap
On Red Hat Enterprise Linux 9:
```
cargo fmt
```
```
$ cargo fmt
```
Copy to Clipboard Toggle word wrap

Note

To change the rustfmt formatting options, create the configuration file rustfmt.toml in the project directory and add your configurations to the file.
