Exn

Provide utilities for dealing with JS exceptions.

anyToExnInternal

Deprecated

Use JsExn.anyToExnInternal instead

RES

let anyToExnInternal: 'a => exn

anyToExnInternal(obj) will take any value obj and wrap it in a 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.

asJsExn

Deprecated

Use JsExn.fromException instead

RES

let asJsExn: exn => option<t>

fileName

Deprecated

Use JsExn.fileName instead

RES

let fileName: t => option<string>

ignore

Deprecated

Use JsExn.ignore instead

RES

let ignore: t => unit
