Module Js.Exn

Provide utilities for dealing with Js exceptions

type t
type exn +=
  1. | Error of t
val asJsExn : exn -> t option
val stack : t -> string option
val message : t -> string option
val name : t -> string option
val fileName : t -> string option
val isCamlExceptionOrOpenVariant : 'a -> bool

internal use only

val anyToExnInternal : 'a -> exn

* anyToExnInternal obj will take any value obj and wrap it * in a Js.Exn.Error if given value is not an exn already. If * obj is an exn, it will return obj without any changes. * * This function is mostly useful for cases where you want to unify a type of a value * that potentially is either exn, a JS error, or any other JS value really (e.g. for * a value passed to a Promise.catch callback) * * IMPORTANT: This is an internal API and may be changed / removed any time in the future. * * 

*   switch (Js.Exn.unsafeAnyToExn("test")) {
*   | Js.Exn.Error(v) =>
*     switch (Js.Exn.message(v)) {
*     | Some(str) => Js.log("We won't end up here")
*     | None => Js.log2("We will land here: ", v)
*     }
*   }
*
