This module provides support for registering inductive scheme builders, declaring schemes and generating schemes on demand

A scheme is either a "mutual scheme_kind" or an "individual scheme_kind"

type mutual
type individual
type 'a scheme_kind
type handle
type scheme_dependency =
  1. | SchemeMutualDep of Names.MutInd.t * mutual scheme_kind
  2. | SchemeIndividualDep of Names.inductive * individual scheme_kind
type mutual_scheme_object_function = Environ.env -> handle -> Names.MutInd.t -> Constr.constr array Evd.in_evar_universe_context
type individual_scheme_object_function = Environ.env -> handle -> Names.inductive -> Constr.constr Evd.in_evar_universe_context

Main functions to register a scheme builder. Note these functions are not safe to be used by plugins as their effects won't be undone on backtracking

val declare_mutual_scheme_object : string -> ?deps:(Environ.env -> Names.MutInd.t -> scheme_dependency list) -> ?aux:string -> mutual_scheme_object_function -> mutual scheme_kind
val declare_individual_scheme_object : string -> ?deps:(Environ.env -> Names.inductive -> scheme_dependency list) -> ?aux:string -> individual_scheme_object_function -> individual scheme_kind

Force generation of a (mutually) scheme with possibly user-level names

val define_individual_scheme : individual scheme_kind -> Names.Id.t option -> Names.inductive -> unit
val define_mutual_scheme : mutual scheme_kind -> (int * Names.Id.t) list -> Names.MutInd.t -> unit

Main function to retrieve a scheme in the cache or to generate it

val lookup_scheme : 'a scheme_kind -> Names.inductive -> Names.Constant.t option

Like find_scheme but does not generate a constant on the fly

val local_lookup_scheme : handle -> 'a scheme_kind -> Names.inductive -> Names.Constant.t option

To be used by scheme-generating functions when looking for a subscheme.

val pr_scheme_kind : 'a scheme_kind -> Pp.t
val declare_definition_scheme : (internal:bool -> univs:Entries.universes_entry -> role:Evd.side_effect_role -> name:Names.Id.t -> Constr.t -> Names.Constant.t * Evd.side_effects) Stdlib.ref
