1. fromBool :: Num a => Bool -> a

   unliftio	UnliftIO.Foreign

   Convert a Haskell Bool to its numeric representation

2. toBool :: (Eq a, Num a) => a -> Bool

   unliftio	UnliftIO.Foreign

   Convert a Boolean in numeric representation to a Haskell value

3. catchBool :: Exception e => (e -> Bool) -> IO a -> (e -> IO a) -> IO a

   extra	Control.Exception.Extra

   Catch an exception if the predicate passes, then call the handler with the original exception. As an example:

   readFileExists x == catchBool isDoesNotExistError (readFile "myfile") (const $ pure "")
   

4. handleBool :: Exception e => (e -> Bool) -> (e -> IO a) -> IO a -> IO a

   extra	Control.Exception.Extra

   Like catchBool but for handle.

5. retryBool :: Exception e => (e -> Bool) -> Int -> IO a -> IO a

   extra	Control.Exception.Extra

   Retry an operation at most n times (n must be positive), while the exception value and type match a predicate. If the operation fails the nth time it will throw that final exception.

6. tryBool :: Exception e => (e -> Bool) -> IO a -> IO (Either e a)

   extra	Control.Exception.Extra

   Like catchBool but for try.

7. catchBool :: Exception e => (e -> Bool) -> IO a -> (e -> IO a) -> IO a

   extra	Extra

   Catch an exception if the predicate passes, then call the handler with the original exception. As an example:

   readFileExists x == catchBool isDoesNotExistError (readFile "myfile") (const $ pure "")
   

8. handleBool :: Exception e => (e -> Bool) -> (e -> IO a) -> IO a -> IO a

   extra	Extra

   Like catchBool but for handle.

9. retryBool :: Exception e => (e -> Bool) -> Int -> IO a -> IO a

   extra	Extra

   Retry an operation at most n times (n must be positive), while the exception value and type match a predicate. If the operation fails the nth time it will throw that final exception.

10. tryBool :: Exception e => (e -> Bool) -> IO a -> IO (Either e a)

    extra	Extra

    Like catchBool but for try.
