3.2. Using rustfmt as a standalone tool Copier lienLien copié sur presse-papiers!
To format a rust source file and all its dependencies with the rustfmt tool:
For Red Hat Enterprise Linux 7:
scl enable rust-toolset-1.35 'rustfmt source-file'
$ scl enable rust-toolset-1.35 'rustfmt source-file'Copy to Clipboard Copied! Toggle word wrap Toggle overflow For Red Hat Enterprise Linux 8:
rustfmt source-file

Replace source-file with path to the source file.
By default, rustfmt modifies the affected files in place without displaying details or creating backups. To change the behavior, use the --write-mode value option. For further details see the help mesage of rustfmt:
For Red Hat Enterprise Linux 7:
scl enable rust-toolset-1.35 'rustfmt --help'
$ scl enable rust-toolset-1.35 'rustfmt --help'Copy to Clipboard Copied! Toggle word wrap Toggle overflow For Red Hat Enterprise Linux 8:
rustfmt --help
$ rustfmt --helpCopy to Clipboard Copied! Toggle word wrap Toggle overflow
Additionally, rustfmt accepts standard input instead of a file and provides its output in standard output.
3.3. Using rustfmt with cargo Copier lienLien copié sur presse-papiers!
