----

Raw Rust FFI bindings to the [`util-linux/libmount`][1] C library.

----

## Supported library version

This crate requires `libmount` version `2.39.2` or later.

## Build dependencies

Install the following packages beforehand to build this crate:

- `util-linux`: to generate Rust bindings from `libmount`'s header files.
- `libclang`: to satisfy the [dependency][2] of [`bindgen`][3] on `libclang`.
- `pkg-config`: to detect system libraries.

This in addition to the [Rust toolchain][4].

### NixOS

This repository contains a configuration file (`flake.nix`) that will
automatically set up a development environment for you. If you have [configured
your system to use flakes][5], issue the following command from the directory
containing the `flake.nix` file.

```console
nix develop
```

The flake will take care of installing the Rust toolchain. Once package
downloads and installations are complete, compile the crate with the command
`cargo build`.

Alternately, you can manually install the required packages temporarily with:

```console
nix-shell -p util-linux.dev libclang.lib pkg-config
```

or permanently with:

```console
nix-env -iA nixos.util-linux.dev nixos.libclang.lib nixos.pkg-config
```

### Alpine Linux

As `root`, issue the following command:

```console
apk add util-linux-dev clang-libclang pkgconfig
```

Install the Rust toolchain via [`rustup`][4] or the package manager, then run
`cargo build`:

```console
apk add cargo
```
