Suppressing Warning in Rescript: Js.Promise.make

When making a promise in Rescript:

let myPromise = Js.Promise.make((~resolve, ~reject) => resolve(. 2))

The ReScript compiler will give a warning on unused variable reject.

Is there a way to suppress this error?

You can bind a parameter to a new name using as, i.e. ~reject as newName, and as with any binding/pattern you can use the wildcard pattern, _, to tell the compiler that you're intentionally ignoring it.

So put together it'd be:

let myPromise = Js.Promise.make((~resolve, ~reject as _) => resolve(. 2))
