struct — 结构体定义

struct() 函数用于定义 C 结构体类型，自动处理字段布局、对齐和紧凑排列。

导入

// JavaScript/TypeScript
import { struct, types } from '@tt23xrstudio/senri_ffi';

# Python
from senri_ffi import struct, types

签名

// JavaScript/TypeScript
const Point = struct({ x: types.float64, y: types.float64 });
const p = new Point({ x: 1.0, y: 2.0 });

# Python
Point = struct({"x": types.float64, "y": types.float64})
p = Point({"x": 1.0, "y": 2.0})
