Radix tree that can do longest-prefix searches on string keys

type 'a t

Radix tree that maps string keys to 'a values

include Ppx_sexp_conv_lib.Sexpable.S1 with type 'a t := 'a t

val t_of_sexp : (Sexplib0__.Sexp.t -> 'a) -> Sexplib0__.Sexp.t -> 'a t

val sexp_of_t : ('a -> Sexplib0__.Sexp.t) -> 'a t -> Sexplib0__.Sexp.t

val empty : 'a t

An empty tree

val insert : string -> 'a -> 'a t -> 'a t

insert key value tree returns a new tree with the mapping key to value

val longest_prefix : string -> 'a t -> 'a option

longest_prefix key tree finds the key k which shares the longest prefix with key and returns the associated value.

val fold : (string -> 'a -> 'b -> 'b) -> 'b -> 'a t -> 'b

fold f initial t folds f over all bindings in t

val is_prefix : string -> string -> bool

is_prefix a b returns true if a is a prefix of b
