new_err: Creates a new error
new_err_from: Creates a new error by converting kind into the matching Error<T> (using a From-trait) and returns it (return Err(Error<T>))
new_err_with: Creates a new error containing the underlaying error
ok_or: Runs $code and returns either the unwrapped result or binds the error to $err and executes $or (or can then access the error using the identifier passed as $err)
rethrow_err: Creates a new error with a sub-error and returns it (return Err(created_error))
some_or: Runs an expression and returns either the unwrapped result or executes $or
throw_err: Creates a new error and returns it (return Err(created_error))
try_err: Runs an expression and returns either the unwrapped result or creates a new error with the returned error as sub-error and returns the new error (return Err(Error<T>))
try_err_from: Runs an expression and returns either the unwrapped result or converts the error into the matching Error<T> (using a From-trait) and returns it (return Err(Error<T>))

Error: A typed-error that contains the error-kind, description, the position (file, line) and an optional sub-error
WrappedError: A generic-error that contains the serialized error-kind, description, the position (file, line) and an optional sub-error
