Struct futures_concurrency::vec::FirstOk

source · [−]

pub struct FirstOk<Fut, T, E>where
    Fut: Future<Output = Result<T, E>>,{ /* private fields */ }

Expand description

Waits for two similarly-typed futures to complete.

Awaits multiple futures simultaneously, returning the output of the futures once both complete.
