System.IO.HVFS.Combinators

Support for combining different HVFS modules together

Copyright (c) 2004-2005 John Goerzen, [e-mail]

Restrictions

data HVFS a => HVFSReadOnly a

Restrict access to the underlying filesystem to be strictly read-only. Any write-type operations will cause an error.

No constructor is required; just say HVFSReadOnly fs to make a new read-only wrapper around the HVFS instance fs.

Constructors
