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 and from databases.
|
|
|
|
Convertible is backed by an extensive test suite and passes tests
|
|
on GHC and Hugs.
