Trait TryFlatJoinIterExt

pub trait TryFlatJoinIterExt<F, I, U>: Iterator
where
    F: Future<Output = Result<I>>,
    I: IntoIterator<IntoIter = U, Item = U::Item>,
    U: Iterator,
{
    // Required method
    fn try_flat_join(self) -> TryFlatJoin<F>;
}

Required Methods

fn try_flat_join(self) -> TryFlatJoin<F>

Returns a future that resolves to a vector of the outputs of the futures in the iterator, or to an error if one of the futures fail.

It also flattens the result.

Unlike Futures::future::try_join_all, this returns the Error that occurs first in the list of futures, not the first to fail in time.
