Rust

Systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.

Format Rust code

rustfmt is a tool for formatting Rust source code. You can install it using Cargo:

$ cargo install rustfmt

This will install an executable into ~/.cargo/bin/. In order to use it, add it into your $PATH variable. In case you are using Bash, follow these steps:

$ echo 'export PATH=$PATH:$HOME/.cargo/bin' >> $HOME/.bashrc
$ source $HOME/.bashrc

Now you can use rustfmt to format either a single file or the whole project:

  • Single file:
    $ rustfmt src/main.rs
    
  • Project:
    $ cargo fmt
