Errors that can be raised at solving

type error =

| Parser_error of string
(*
Error used at parser loading
*)
| Lexical_error of Loc.t * string
(*
Error used by the lexer
*)
| Syntax_error of Loc.t * string
(*
Error used by the parser
*)
| Typing_error of Loc.t * typing_error
(*
Error used at typing
*)
| Run_error of run_error
(*
Error used during solving
*)
| Warning_as_error

All types of error that can be raised

Exceptions

exception Error of error

Raising exceptions functions

val error : error -> 'a

Raise the input error as Error

val typing_error : typing_error -> Loc.t -> 'a

Raise the input typing_error as Typing_error

val run_error : run_error -> 'a

Raise the input run_error as Run_error

val warning_as_error : unit -> unit

Raise Warning_as_error as Error if the option warning-as-error is set This function can be use after warning

Printing

val report : Stdlib.Format.formatter -> error -> unit

Print a message on the formatter corresponding to the error
