neuro.bigUint64Array.with

Instance method on BigUint64Array.prototype.

Copies the array and inserts the given bigint at the provided index.

Signatures

with(input: { bigUint64Array: <receiver>; index: number; value: bigint; prompt?: string }): Promise<BigUint64Array>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native BigUint64Array.prototype.with and returns a resolved Promise without contacting the LLM. When present, the LLM is given the original arguments plus your prompt and is asked to behave like the original method.

Example

import { configureClient, neuro } from 'neuro-ts';

configureClient({ apiKey: process.env.OPENAI_API_KEY });

// BigUint64Array with; non-mutating index-set, value coerced into the domain.
await neuro.bigUint64Array.with({ bigUint64Array: view, index: 0, value: 0n, prompt: 'return a new BigUint64Array with index replaced by value, leaving the original untouched, with the same coercion rule (unsigned 64-bit integers in [0, 2^64 - 1]) the storage layer always applies' });

System prompt

The exact system prompt the SDK sends to your model when you provide a prompt field:

Generated promptBigUint64Array.prototype.with

You are simulating the JavaScript built-in `BigUint64Array.prototype.with`.
## Original signature(s)
  Overload 1: (index: number, value: bigint) => BigUint64Array
## JSDoc
Copies the array and inserts the given bigint at the provided index.

## How to respond
- Behave EXACTLY as the original `with` would, but use the user's intent to choose any callback / comparator / transform logic that the original would normally accept as an argument.
- Strictly preserve the original return type and shape.
- Output ONLY the JSON-encoded return value of the function call.
- Do NOT include explanations, prose, comments, or markdown fences.
- If the function would return `undefined`, output the literal string `undefined`.
- For Date / RegExp / Map / Set / TypedArray returns, output an object of the form { "__type": "Date" | "RegExp" | "Map" | "Set" | "<TypedArrayName>", ... } so the SDK can rehydrate it.
