val get : t -> key -> elt

get db k returns the value associated to k.

val put : ?flags:PutFlags.t -> t -> key -> elt -> unit

put db k v associates the key k to the value v in the database db.

val append : t -> key -> elt -> unit

append db k v append k, v at the end of the database db without performing comparisons.

Should only be used to quickly add already-sorted data to the database.

val remove : ?elt:elt -> t -> key -> unit

remove db k removes k from db.

If the database accepts duplicates:

module Txn : sig ... end

A series of operation performed atomically.

module Cursor : sig ... end

val drop : ?delete:bool -> t -> unit

val compare : t -> key -> key -> int
