Function std::env::home_dir

pub fn home_dir() -> Option<PathBuf>

Returns the path of the current user’s home directory if known.

Unix

• Returns the value of the ‘HOME’ environment variable if it is set (including to an empty string).
• Otherwise, it tries to determine the home directory by invoking the getpwuid_r function using the UID of the current user. An empty home directory field returned from the getpwuid_r function is considered to be a valid value.
• Returns None if the current user has no entry in the /etc/passwd file.

Windows

• Returns the value of the ‘HOME’ environment variable if it is set (including to an empty string).
• Otherwise, returns the value of the ‘USERPROFILE’ environment variable if it is set (including to an empty string).
• If both do not exist, GetUserProfileDirectory is used to return the path.

Examples

use std::env;

match env::home_dir() {
    Some(path) => println!("Your home directory, probably: {}", path.display()),
    None => println!("Impossible to get your home dir!"),
}
