Exn

Provide utilities for dealing with JS exceptions.

anyToExnInternal

Deprecated

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

RES

let asJsExn: exn => option<t>

fileName

Deprecated

RES

let fileName: t => option<string>

ignore

Deprecated

RES

let ignore: t => unit

ignore(exn) ignores the provided exn and returns unit.

This helper is useful when you want to discard a value (for example, the result of an operation with side effects) without having to store or process it further.
