# Rust `rust`

!!! important "This section is rendered asynchronously by default"

!!! info
    [**Rust**](https://www.rust-lang.org) is a systems programming language that is focused on safety, speed, and concurrency.

The `rust` section displays the version of Rust.

This section is displayed only when the current directory is within a Rust project, meaning:

* Upsearch finds `Cargo.toml` file
* The current directory contains any `.rs` file

## Displaying verbose version

By default, this section will strip all of the suffixes from the version. For example, `1.42.0-nightly.2020-06-09` will be displayed as `1.42.0`. To disable that behavior use a `SPACESHIP_RUST_VERBOSE_VERSION` environment variable.

```zsh title=".zshrc"
# Display verbose version
SPACESHIP_RUST_VERBOSE_VERSION=true
```
