Conversion Functions (uses closures, lazy strategy)

Sourcetype conversion_test = Univ.Constraints.t -> Univ.Constraints.t

Sourceval pb_is_equal : Evd.conv_pb -> bool

  ?pb:Evd.conv_pb ->
  ?ts:TransparentState.t ->
  Environ.env ->
  Evd.evar_map ->
  EConstr.constr ->
  EConstr.constr ->
  bool

check_conv Checks universe constraints only. pb defaults to CUMUL and ts to a full transparent state.

Source

val infer_conv : 
  ?catch_incon:bool ->
  ?pb:Evd.conv_pb ->
  ?ts:TransparentState.t ->
  Environ.env ->
  Evd.evar_map ->
  EConstr.constr ->
  EConstr.constr ->
  Evd.evar_map option

infer_conv Adds necessary universe constraints to the evar map. pb defaults to CUMUL and ts to a full transparent state.

raises UniverseInconsistency
iff catch_incon is set to false, otherwise returns false in that case.

Source

val infer_conv_ustate : 
  ?catch_incon:bool ->
  ?pb:Evd.conv_pb ->

  EConstr.constr ->
  EConstr.constr ->

Source

val infer_conv_gen : 
  (Evd.conv_pb ->
    l2r:bool ->
    Evd.evar_map ->
    TransparentState.t ->
    (Constr.constr, Evd.evar_map) Reduction.generic_conversion_function) ->
  ?catch_incon:bool ->
  ?pb:Evd.conv_pb ->
  ?ts:TransparentState.t ->
  Environ.env ->
  Evd.evar_map ->
  EConstr.constr ->
  EConstr.constr ->
  Evd.evar_map option

infer_conv_gen behaves like infer_conv but is parametrized by a conversion function. Used to pretype vm and native casts.
