Describe the bug
TimeoutInfo
is an object that is passed to the with
callback of TimeoutConfig
(timeout
operator's config object). It has lastValue
field which seems to be null
regardless of what was the last value emitted before the timeout occurred.
Expected behavior
lastValue
is expected to contain a value emitted right before the timeout firing.
Reproduction code
import { interval, concat, take, EMPTY, timeout } from 'rxjs';
const fast = interval(10).pipe(take(5));
const slow = interval(1000).pipe(take(5));
const replacement = info => {console.log(info); return EMPTY }
const withTimeout = concat(fast, slow).pipe(timeout({each: 500, with: replacement}))
withTimeout.subscribe(console.log);
