Say i have something like:
let keys: Vec<Key> = vec![key1, key2, key3]; let data = keys .into_iter() .map(Data::load) .collect::<Result<Vec<Data>, _>>?;
Now suppose I convert
Data::load to an
async fn. Is there any nice way to rewrite the above collect line above to somehing that lets me await a single
Result<Vec<Data>, E> ?
Can it be done with the std library (rust 1.48.0), or with the
futures crate, or do I have to rewrite it as a loop?
