Module `Effect.Shallow`Source

Sourcetype ('a, 'b) continuation

('a,'b) continuation is a delimited continuation that expects a 'a value and returns a 'b value.

Sourceval fiber : ('a -> 'b) -> ('a, 'b) continuation

fiber f constructs a continuation that runs the computation f.

Sourcetype ('a, 'b) handler = {

retc : 'a -> 'b;
exnc : exn -> 'b;
effc : 'c. 'c t -> (('c, 'a) continuation -> 'b) option;

}

('a,'b) handler is a handler record with three fields -- retc is the value handler, exnc handles exceptions, and effc handles the effects performed by the computation enclosed by the handler.

Sourceval continue_with : ('c, 'a) continuation -> 'c -> ('a, 'b) handler -> 'b

continue_with k v h resumes the continuation k with value v with the handler h.

raises Continuation_already_resumed
if the continuation has already been resumed.

Sourceval discontinue_with : ('c, 'a) continuation -> exn -> ('a, 'b) handler -> 'b

discontinue_with k e h resumes the continuation k by raising the exception e with the handler h.

raises Continuation_already_resumed
if the continuation has already been resumed.

val discontinue_with_backtrace : 
  ('a, 'b) continuation ->
  exn ->
  Printexc.raw_backtrace ->
  ('b, 'c) handler ->
  'c

discontinue_with k e bt h resumes the continuation k by raising the exception e with the handler h using the raw backtrace bt as the origin of the exception.

raises Continuation_already_resumed
if the continuation has already been resumed.

Sourceval get_callstack : ('a, 'b) continuation -> int -> Printexc.raw_backtrace

get_callstack c n returns a description of the top of the call stack on the continuation c, with at most n entries.
