## Declaration

struct NSDKBuffer

## Summary

A buffer containing binary data for NSDK operations.
`NSDKBuffer` provides a safe wrapper around binary data buffers used by
various NSDK features. It handles memory management and provides convenient
access to buffer data.

## Overview

NSDK buffers are used for:

- Image data transfer
- Mesh data storage
- Configuration data
- Any binary data that needs to be passed between Swift and the native NSDK layer

## Example Usage

```swift
// Create buffer from Swift Data
let imageData = UIImage(named: "texture")?.pngData()
let buffer = NSDKBuffer(data: imageData!)
// Access buffer data
print("Buffer size: \(buffer.dataSize) bytes")
// Use buffer with NSDK APIs
let status = someArdkFunction(buffer: buffer)
```

## Memory Management

`NSDKBuffer` automatically manages memory allocation and deallocation.
When created from Swift `Data`, it maintains a reference to prevent premature deallocation.

---

## Constructors

### Constructor

init(data: Data)

---

### Overload

init(data: UnsafePointer<UInt8>, dataSize: UInt32)

---

## Properties

| Name | Type | Summary |
| --- | --- | --- |
| let data | UnsafePointer<UInt8> | Pointer to the buffer's binary data.This provides direct access to the buffer's contents. The data remainsvalid as long as the `NSDKBuffer` instance exists. |
| let dataSize | UInt32 | Size of the buffer data in bytes.This indicates the total number of bytes available in the buffer. |
| let owner | ResourceOwner? | Resource owner for memory management.This ensures the buffer's memory is properly managed and deallocatedwhen the buffer is no longer needed. |
