+description: |
+    Rust is a modern memory-safe systems programming language focused on
+    performance and reliability.
+
+    This image is a chiselled Ubuntu rock based on Ubuntu 25.04. It contains
+    a minimal Rust 1.84 toolchain and Cargo build system which can be used to
+    build a wide variety of Rust applications. It also includes a minimal
+    GCC toolchain to custom build steps in Cargo builds.
+    
+    Any additional dependencies can be either mounted at runtime or installed
+    with the apt installation included in this rock.

+
+    To mount a directory with your Rust project and build it with Cargo:
+
+    ```bash
+    docker run -it --rm \
+      -v /path/to/your/rust/project:/work \
+      --workdir /work \
