Efficient static string dictionaries. By static, we mean that new key-value pairs cannot be added after the dictionary is created.

This uses the algorithm the OCaml compiler uses for pattern matching on strings.

type 'a t

val hash_fold_t : 
  (Base.Hash.state -> 'a -> Base.Hash.state) ->
  Base.Hash.state ->
  'a t ->
  Base.Hash.state

val compare : ('a -> 'a -> Base.int) -> 'a t -> 'a t -> Base.int

val sexp_of_t : ('a -> Base.Sexp.t) -> 'a t -> Base.Sexp.t

We don't use [@@deriving sexp], to avoid a circular dependency.

val t_of_sexp : (Base.Sexp.t -> 'a) -> Base.Sexp.t -> 'a t

val of_alist : (Base.string * 'a) Base.list -> ('a t, Base.string) Caml.result

Creates a dictionary from an association list. It is an error for the list to contain duplicate keys.

val of_alist_exn : (Base.string * 'a) Base.list -> 'a t

val find : 'a t -> Base.string -> 'a Base.option

val find_exn : 'a t -> Base.string -> 'a

val to_alist : 'a t -> (Base.string * 'a) Base.list
