home_dir, the home directory of the current user in Rust

examples/hello.rs

fn main() {
    println!("Hello World");
}

Create a crate

Cleverly (or confusingly ?) call the crate home-dir.

cargo new home-dir
cd home-dir

Add directories crate as a dependency

The directories crate seems to offer what we need here.

cargo add directories

This will update the Cargo.toml file:

examples/home-dir/Cargo.toml

[package]
name = "home-dir"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
directories = "5.0.1"

Source code

examples/home-dir/src/main.rs

fn main() {
    let bd = directories::BaseDirs::new().unwrap();
    let home_dir = bd.home_dir();

    println!("home_dir: {:?}", home_dir);
}

Running it:

cargo run


home_dir: "/home/gabor"

Indeed that's my home directory on this computer.
