Functions

func Catch

func Catch(err *error)

Catch recovers from panics and attempts to convert the value into an error. Must be used directly in a defer statement, can not be called elsewhere. Set 'err' to the address of the return value, typically with a named return error value. Example: defer exception.Catch(&err)

func CatchHandler

func CatchHandler(fn func(err error))

CatchHandler is the same as Catch, but enables custom error handling after recovering.
