Function crev_common::sanitize_name_for_fs

pub fn sanitize_name_for_fs(s: &str) -> PathBuf

Takes a name and converts it to something safe for use in paths etc.

Examples

// Pass through when able
assert_eq!(sanitize_name_for_fs("lazy_static"), Path::new("lazy_static-Bda78Hdy9hiPaGTczi9ADA"));

// Hash reserved windows filenames (or any other 3 letter name)
assert_eq!(sanitize_name_for_fs("CON"), Path::new("CON--NhvzH8hSGvoA4DSfBFbpg"));

// Hash on escaped chars to avoid collisions
assert_eq!(sanitize_name_for_fs("://baluga.?io"), Path::new("___baluga__io-7zPdDFu-AyMMKrFrpmY7BQ"));

// Limit absurdly long names.  Combining a bunch of these can still run into filesystem limits however.
