FlatMapStream

dfir_pipes::push

Struct FlatMapStream 

Source 
pub struct FlatMapStream<Next, Func, St, Meta>
where
    St: Stream,
{ /* private fields */ }
Expand description

Push combinator that maps each item to a stream and pushes each element downstream.

When the inner stream yields Poll::Pending, this operator yields as well.
