val resolve_one_typeclass : ?db:Hints.hint_db -> Environ.env -> Evd.evar_map -> EConstr.types -> Evd.evar_map * EConstr.constr

Tries to find a solution for the given type. Raises Not_found it it fails.

type solver = {
  1. solver : ?db:Hints.hint_db -> Environ.env -> Evd.evar_map -> depth:int option -> unique:bool -> best_effort:bool -> goals:Evar.t list -> bool * Evd.evar_map;
}
type condition = Environ.env -> Evd.evar_map -> Evar.Set.t -> bool
type tc_solver = solver * condition

A tc_solver is made of a solver and a condition telling when the the solver should be executed instead of Rocq's one
