readFromPathPiece :: Read s => Text -> Maybe s Source
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 Source
See the documentation for readFromPathPiece.
Since 0.2.1.
