Expand description
Returns the path to the user’s home directory.
The returned value depends on the operating system and is either a Some
, containing a value from the following table, or a None
.
Platform | Value | Example |
---|---|---|
Linux | $HOME | /home/alice |
macOS | $HOME | /Users/Alice |
Windows | {FOLDERID_Profile} | C:\Users\Alice |
Linux and macOS:
- Use
$HOME
if it is set and not empty. - If
$HOME
is not set or empty, then the functiongetpwuid_r
is used to determine the home directory of the current user. - If
getpwuid_r
lacks an entry for the current user id or the home directory field is empty, then the function returnsNone
.
Windows:
This function retrieves the user profile folder using SHGetKnownFolderPath
.
All the examples on this page mentioning $HOME
use this behavior.
Note: This function’s behavior differs from std::env::home_dir
,
which works incorrectly on Linux, macOS and Windows.
