Description

Support for combining different HVFS modules together

Synopsis

data HVFS a => HVFSReadOnly a = HVFSReadOnly a
data HVFS a => HVFSChroot a
newHVFSChroot :: HVFS a => a -> FilePath -> IO (HVFSChroot a)

Restrictions

data HVFS a => HVFSReadOnly a Source #

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

HVFSReadOnly a
