include Hmap.S with type 'a Key.info = string * ('a -> Sexplib.Sexp.t)

Keys

type 'a key

The type for keys whose lookup value is of type 'a.

module Key : sig ... end

Keys.

Maps

type t

The type for heterogeneous value maps.

val empty : t

empty is the empty map.

val is_empty : t -> bool

is_empty m is true iff m is empty.

val mem : 'a key -> t -> bool

mem k m is true iff k is bound in m.

val add : 'a key -> 'a -> t -> t

add k v m is m with k bound to v.

val singleton : 'a key -> 'a -> t

singleton k v is add k v empty.

val rem : 'a key -> t -> t

rem k m is m with k unbound.

val find : 'a key -> t -> 'a option

find k m is the value of k's binding in m, if any.

val get : 'a key -> t -> 'a

get k m is the value of k's binding in m.

raises Invalid_argument
if k is not bound in m.

type binding =

| B : 'a key * 'a -> binding

The type for bindings.

val iter : (binding -> unit) -> t -> unit

iter f m applies f to all bindings of m.

val fold : (binding -> 'a -> 'a) -> t -> 'a -> 'a

fold f m acc folds over the bindings of m with f, starting with acc

val for_all : (binding -> bool) -> t -> bool

for_all p m is true iff all bindings of m satisfy p.

val exists : (binding -> bool) -> t -> bool

exists p m is true iff there exists a bindings of m that satisfies p.

val filter : (binding -> bool) -> t -> t

filter p m are the bindings of m that satisfy p.

val cardinal : t -> int

cardinal m is the number of bindings in m.

val any_binding : t -> binding option

any_binding m is a binding of m (if not empty).

val get_any_binding : t -> binding

get_any_binding m is a binding of m.

raises Invalid_argument
if m is empty.

val sexp_of_t : t -> Sexplib.Sexp.t

val find_exn : 'a key -> t -> 'a
