Function: chainUntil()
chainUntil<
T>(startArb,chainer):Arbitrary<T>
Defined in: packages/fast-check/src/arbitrary/chainUntil.ts:155
Build an arbitrary by iteratively chaining arbitraries until the chainer returns undefined.
Starting from a value produced by startArb, the chainer function is called with the current value
to produce the next arbitrary. This process repeats until chainer returns undefined.
The final value in the chain is the one produced by this arbitrary.
The implementation is fully iterative (non-recursive) and supports shrinking.
Type Parameters

T |
Parameters
| Parameter | Type | Description |
|---|---|---|
startArb | Arbitrary<T> | The starting arbitrary producing the initial value |
chainer | (prev) => Arbitrary<T> | undefined | A function called with the current value that returns either the next arbitrary to generate from or undefined to stop the chain |
Returns
Arbitrary<T>
An arbitrary producing the last value in the chain
