exhaustMap<R> method
Emits and completes values from a higher-order Observable retrieved by
projecting the values of the source to higher-order Observables.
Subscribes to at most concurrent
sources, drops observables exceeding
this threshold.
Implementation
Observable<R> exhaustMap<R>(Map1<T, Observable<R>> project,
{int concurrent = 1}) =>
ExhaustObservable<T, R>(this, project, concurrent);
