Result types

datadata FailureReason
#
Instances4Eq, Show, Exception, ToBrickWidget

A wrapper type for exceptions with attached callstacks. Haskell doesn't currently offer a way to reliably get a callstack from an exception, but if you can throw (or catch+rethrow) this type then we'll unwrap it and present the callstack nicely.
