This library is intended to be used as a drop-in replacement for the primitive library in test environments. It adds bounds-checking to all functions in primitive that are able to cause segfaults. It is not recommended to use this library in production. However, if you are testing a library or application you wrote that uses primitive, you can temporarily replace your primitive dependency with primitive-checked, and your segfaults will become normal Haskell exceptions that you can hunt down with GHC's stack trace facilities. The versioning for this library matches the version of primitive that is targeted. The first three numbers of the version match the version of primitive. The fourth number is used for bug fixes. This packages deviates slightly from the PVP in that functions can be added to the API with only a bump to the fourth number.
