# Prelude Rust
|
|
|
|
!!! Note
|
|
|
|
This module builds on top of the shared [Programming](programming.md) module.
|
|
|
|
## Package Prerequisites
|
|
|
|
For the proper functioning of this module, you'll need to install the
|
|
following packages in your system:
|
|
|
|
* `rustc` (Rust compiler)
|
|
* `cargo` (Rust package manager)
|
|
* `rustfmt` (Rust tool for formatting code)
|
|
* `racer` (Rust completion tool, not necessary if `prelude-lsp` is enabled)
|
|
* `rls` (Rust Language Server, if the `prelude-lsp` feature is enabled)
|
|
|
|
## Rust Mode
|
|
|
|
Emacs comes with Rust programming support through the built-in
|
|
`rust-mode`. Whenever you are editing Rust code run <kbd>C-h m</kbd> to
|
|
look at the Rust mode key bindings.
|
|
|
|
## Syntax checking
|
|
|
|
Prelude ships with [Flycheck](https://github.com/flycheck/flycheck),
|
|
an on the fly syntax checker. Flycheck has support for Rust. Rust is
|
|
automatically setup in flycheck, by executing
|
|
`flycheck-rust-setup`. If the current file is part of a Cargo project,
|
|
flycheck is configured according to the Cargo project layout.
|
|
|
|
## Cargo integration
|
|
|
|
Along with `rust-mode`, `cargo-minor-mode` is also configured. You can
|
|
give cargo commands from inside the buffer to run cargo commands, like
|
|
<kbd>C-c C-c C-b</kbd> for `cargo-process-build`, <kbd>C-c C-c
|
|
C-t</kbd> for `cargo-process-test` and <kbd>C-c C-c C-r</kbd> for
|
|
`cargo-process-run`
