Module `Structures.CanonicalSolution`Source

The canonical solution of a problem (proj,val) is a global constant = fun abs : abstractions_ty => body and body = RecodConstructor params canon_values and the canonical value corresponding to val is val cvalue_arguments. It is possible that val is one of the abs abstractions, eg Default_cs, and in that case cvalue_abstraction = Some i

Sourcetype t = {

constant : EConstr.t;
abstractions_ty : EConstr.t list;
body : EConstr.t;
nparams : int;
params : EConstr.t list;
cvalue_abstraction : int option;
cvalue_arguments : EConstr.t list;

val find : 
  Environ.env ->
  Evd.evar_map ->
  (Names.GlobRef.t * ValuePattern.t) ->
  Evd.evar_map * t

find (p,v) returns a s such that p s = v. The solution s gets a fresh universe instance and is decomposed into bits for consumption by evarconv. Can raise Not_found on failure

val is_open_canonical_projection : 
  Environ.env ->
  Evd.evar_map ->
  EConstr.t ->
  bool

is_open_canonical_projection env sigma t is true if t is a FieldName applied to term which is not a constructor. Used by evarconv not to unfold too much and lose a projection too early
