val try_with : ?backtrace:bool -> (unit -> 'a) -> 'a t
try_with f catches exceptions thrown by f and returns them in the Result.t as an Error.t. try_with_bind is like try_with, except that f can throw exceptions or return an Error directly, without ending up with a nested error; it is equivalent to Result.join (try_with f).
val try_with_bind : ?backtrace:bool -> (unit -> 'a t) -> 'a t
val ok_exn : 'a t -> 'a
ok_exn t throws an exception if t is an Error, and otherwise returns the contents of the Ok constructor.
val of_exn : ?backtrace:[ `Get | `This of string ] -> exn -> 'a t
of_exn exn is Error (Error.of_exn exn).
val error : string -> 'a -> ('a -> Sexplib.Sexp.t) -> 'b t
error message value sexp_of_value constructs an Error.t and returns it as a Result.Error. error_string is a sepcial case with 'a = unit.
val error_string : string -> 'a t
val unimplemented : string -> 'a t
unimplemented name returns a standard error value for an unimplemented value.
