I don't know of any implementations using rest arguments (...more
).
function (err, key, value)
is correct, but some of our tests do rely on !arguments.length
to check if the iterator has ended - rather than key === undefined
. So this wouldn't work:
return self._next(function (err, key, value) {
self._nexting = false
callback(err, key, value)
})
from abstract-leveldown.
okay cool; I'm was just making sure I can type the next as:
interface IteratorNextCallBack<TKey, TValue> {
(err: any, key: TKey, value: TValue): void;
}
interface Iterator<TKey, TValue> {
next(callback: IteratorNextCallBack<TKey, TValue>);
end(callback: (err: any) => void): void;
/** don't complain about untyped access */
[index: string]: any;
}
from abstract-leveldown.
