pub fn home() -> Result<Utf8PathBuf, RkError>Expand description
The home directory, from the environment.
A home that is not UTF-8 refuses rather than proceeding: the record names its destinations as text, so a path it cannot write down is a path it cannot later vouch for.
ยงErrors
Returns RkError::Refused when no home variable is set, and when the
home directory is not UTF-8.
