The Traced_result_syntax module is similar to the Result_syntax module with the following differences:

val return : 'a -> ('a, 'error) result

val return_unit : (unit, 'error) result

val return_none : ('a option, 'error) result

val return_some : 'a -> ('a option, 'error) result

val return_nil : ('a list, 'error) result

val return_true : (bool, 'error) result

val return_false : (bool, 'error) result

val fail : 'error -> ('a, 'error trace) result

fail e is (Error (Trace.make e)) where Trace is the Traced_sigs.Trace module that provides the trace type and functions.

val let* : ('a, 'e) result -> ('a -> ('b, 'e) result) -> ('b, 'e) result

val and* : 
  ('a, 'e trace) result ->
  ('b, 'e trace) result ->
  ('a * 'b, 'e trace) result

val let+ : ('a, 'e) result -> ('a -> 'b) -> ('b, 'e) result

val and+ : 
  ('a, 'e trace) result ->
  ('b, 'e trace) result ->
  ('a * 'b, 'e trace) result

val join : (unit, 'error trace) result list -> (unit, 'error trace) result

val all : ('a, 'error trace) result list -> ('a list, 'error trace) result

val both : 
  ('a, 'error trace) result ->
  ('b, 'error trace) result ->
  ('a * 'b, 'error trace) result
