Function ron_from_path_recoverable 

pub fn ron_from_path_recoverable<T: Default + for<'a> Deserialize<'a>>(
    path: &Path,
) -> T

Load settings from ron in a recoverable manner. Requires #[serde(default)].

Lines with parse errors are deleted and parsing is attempted again; this is repeated until either parsing succeeds or the string is empty. If there was a parse error, the original file gets renamed to have the extension invalid.ron. Otherwise the disk is not written to.
