Function return_success 

pub unsafe fn return_success(
    data: Value,
    result_buf: *mut *mut u8,
    result_len: *mut usize,
) -> i32

Return a success result to the framework

This handles all the unsafe memory management details:

• Converts the value to JSON
• Allocates a buffer
• Shrinks to minimize memory usage
• Returns the pointer and capacity to the framework

Safety

The caller must ensure that:

• result_buf points to valid, properly aligned memory for writing a pointer
• result_len points to valid, properly aligned memory for writing a usize
• These pointers remain valid for the duration of the call
• The pointers are not aliased (no other mutable references exist)

Example

unsafe {
    let result = json!({"status": "ok"});
    return return_success(result, result_buf, result_len);
}
