Struct PolicyEnforcedFs 

pub struct PolicyEnforcedFs { /* private fields */ }

A filesystem provider that wraps another and enforces a RuntimePolicy.

All read operations check policy.is_path_readable(); all write operations check policy.is_path_writable(). If the check fails, io::ErrorKind::PermissionDenied is returned.
