Description:
Typeclasses and instances for converting between types, documentation
convertible provides a typeclass with a single function that is designed to help convert between different types: numeric values, dates and times, and the like. The conversions perform bounds checking and return a pure Either value. This means that you need not remember which specific function performs the conversion you desire. . Also included in the package are optional instances that provide conversion for various numeric and time types, as well as utilities for writing your own instances. . Finally, there is a function that will raise an exception on bounds-checking violation, or return a bare value otherwise, implemented in terms of the safer function described above. . Convertible is also used by HDBC 2.0 for handling marshalling of data to/from databases. . Convertible is backed by an extensive test suite and passes tests on GHC and Hugs. . This package provides documentation on the Convertible API.
