readFromPathPiece :: Read s => Text -> Maybe s #

A function for helping generate free `PathPiece` instances for enumeration data types that have derived `Read` and `Show` instances. Intended to be used like this:

    data MyData = Foo | Bar | Baz
      deriving (Read,Show)
    instance PathPiece MyData where
      fromPathPiece = readFromPathPiece
      toPathPiece = showToPathPiece

Since 0.2.1.

showToPathPiece :: Show s => s -> Text #

See the documentation for `readFromPathPiece`.

Since 0.2.1.
