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 : Format.formatter -> error -> unit

Print a message on the formatter corresponding to the error
