withLatestFrom()
Function
withLatestFrom<I, R>(read:
R):MaybeCancellingPipeOperator<I, [I,ReadReturn<R>],IsCancellingRead<R>>
Combines the latest result of the passed Read.
ts
// without a cancelling Read
declare const read1: Read<string>;
declare const read2: Read<number>;
const read: Read<[string, number]> = read1.pipe(withLatestFrom<string, typeof read2>(read2));ts
// with a cancelling Read
declare const read1: Read<string>;
declare const read2: Read<number, true>;
const read: Read<[string, number], true> = read1.pipe(withLatestFrom<string, typeof read2>(read2));Observable Behavior:
Works exactly like withLatestFrom of RxJS.
Sync Behavior:
Retrieves sync value of passed Read. If the passed read canceled the chain, then the chain will be canceled.
