Struct grass::NullFs

pub struct NullFs;

A file system implementation that acts like it’s completely empty.

This may be useful for security as it denies all access to the file system (so @import is prevented from leaking anything); you’ll need to use from_string for this to make any sense (since from_path would fail to find a file).
