module BatResult: sig .. end

Monadic results of computations that can raise exceptions

type ('a, 'b) t = ('a, 'b) BatStd.result

The type of a result

val catch : ('a -> 'b) -> 'a -> ('b, exn) BatStd.result

Execute a function and catch any exception as a !result

val of_option : 'a option -> ('a, unit) BatStd.result

val to_option : ('a, 'b) BatStd.result -> 'a option

Convert a result to an option

val bind : ('a, 'b) BatStd.result ->
       ('a -> ('c, 'b) BatStd.result) -> ('c, 'b) BatStd.result

Monadic composition.

bind r f proceeds as f x if r is Ok x, or returns r if r is an error.

val (>>=) : ('a, 'b) BatStd.result ->
       ('a -> ('c, 'b) BatStd.result) -> ('c, 'b) BatStd.result
