bugsnagException :: Text -> Text -> [BugsnagStackFrame] -> BugsnagException

Construct a throwable BugsnagException

Note that Message is optional in the API, but we consider it required because that's just silly. To include a stack frame from the location of construction via Template Haskell, see currentStackFrame.

bugsnagExceptionFromSomeException :: SomeException -> BugsnagException

Construct a BugsnagException from a SomeException

BugsnagExceptions are left as-is, and ErrorCall exceptions are parsed for HasCallStack information to use as stacktrace. Otherwise, we attempt to determine errorClass and we use displayException as message.

>>> import Control.Arrow
>>> import System.IO.Error
>>> (beErrorClass &&& beMessage) $ bugsnagExceptionFromSomeException $ toException $ userError "Oops"
("IOException",Just "user error (Oops)")
