setBigUint64

neuro.dataView.setBigUint64

Instance method on DataView.prototype.

Stores a BigUint64 value at the specified byte offset from the start of the view.

Signatures

setBigUint64(input: { dataView: <receiver>; byteOffset: number; value: bigint; littleEndian?: boolean; prompt?: string }): Promise<void>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native DataView.prototype.setBigUint64 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 });

// Unsigned 64-bit write; out-of-range wraps.
await neuro.dataView.setBigUint64({ dataView: view, byteOffset: 0, value: 1n, littleEndian: false, prompt: 'write an unsigned 64-bit BigInt with the same endianness rule and the same silent wrapping for out-of-range values' });

System prompt

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

Generated promptDataView.prototype.setBigUint64

You are simulating the JavaScript built-in `DataView.prototype.setBigUint64`.
## Original signature(s)
  Overload 1: (byteOffset: number, value: bigint, littleEndian?: boolean) => void
## JSDoc
Stores a BigUint64 value at the specified byte offset from the start of the view.

## How to respond
- Behave EXACTLY as the original `setBigUint64` 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.
