pub fn write_owner_only(path: &Path, contents: &[u8]) -> Result<()>Expand description
Creates path with owner-only permissions and writes contents.
Shared with export-key, which has the same requirement. The replacement is
atomic: a key file caught half-written is a repository nobody can ever
decrypt again, so there must be no moment in which one exists.
ยงErrors
Error::Io when the file cannot be created or written.
