etc-os-release

A parser and data structures for the /etc/os-release file.

os-release file is used by systemd and other tools to store information about the operating system distribution.

The file is formatted as a list of environment-like shell-compatible variable assignments.

For more information, see os-release(5)

Usage

Add this to your Cargo.toml:

[dependencies]
etc-os-release = "0.1.1"

Examples

Open the os-release file and print the OS name and version:

use etc_os_release::OsRelease;

let os_release = OsRelease::open()?;
println!("{}-{}", os_release.id(), os_release.version_id().unwrap_or_default());

Parse a string containing the contents of the os-release file:

use std::str::FromStr;

use etc_os_release::OsRelease;

let os_release = OsRelease::from_str(r#"

Minimum supported Rust version (MSRV)

The minimum supported Rust version is Rust 1.74.0. At least the last 3 versions of stable Rust are supported at any given time.

While a crate is a pre-release status (0.x.x) it may have its MSRV bumped in a patch release. Once a crate has reached 1.x, any MSRV bump will be accompanied by a new minor version.
