Module `Meta_conv.Result`Source

Sourcetype ('a, 'error) t = ('a, 'error) result

monadic ops

Sourceval bind : ('a, 'error) t -> ('a -> ('b, 'error) t) -> ('b, 'error) t

Sourceval (>>=) : ('a, 'error) t -> ('a -> ('b, 'error) t) -> ('b, 'error) t

Sourceval fmap : ('a -> 'b) -> ('a, 'error) t -> ('b, 'error) t

Sourceval (>>|) : ('a, 'error) t -> ('a -> 'b) -> ('b, 'error) t

Same as fmap but as a binop

Sourceval map : ('a -> ('b, 'error) t) -> 'a list -> ('b list, 'error) t

Sourceval mapi : (int -> 'a -> ('b, 'error) t) -> 'a list -> ('b list, 'error) t

Sourceval fail : 'error -> ('a, 'error) t

Sourceval catch : (fail:('error -> 'exn) -> 'a) -> ('a, 'error) t

Sourceval catch_exn : (unit -> 'a) -> ('a, exn) t

Sourceval result : ('a -> 'b) -> ('error -> 'b) -> ('a, 'error) t -> 'b

same as Haskell's either
