open Pattern
(** Discrimination nets with bounded depth. *)
(** This module registers actions (typically tactics) mapped to patterns *)
(** Patterns are stocked linearly as the list of its node in prefix
order in such a way patterns having the same prefix have this common
prefix shared and the seek for the action associated to the patterns
that a term matches are found in time proportional to the maximal
number of nodes of the patterns matching the term. The [TransparentState.t]
indicates which constants and variables can be considered as rigid.
These dnets are able to cope with existential variables as well, which match
[Everything]. *)
