Struct ApiVersion 

pub struct ApiVersion(/* private fields */);

API 版本号

内部以 u32 存储，支持 v1、v2 等数字版本。 不支持语义化版本（如 v1.2.3），保持 API 版本协商简单。

Implementations

impl ApiVersion

pub const fn new(version: u32) -> Self

创建新的 API 版本号

pub fn as_u32(&self) -> u32

获取版本号数值

pub fn parse(s: &str) -> Option<Self>

从字符串解析版本号

支持格式：

• "1" / "2" → 纯数字
• "v1" / "v2" → v 前缀
• "version=1" → query 参数格式

pub fn to_vstring(&self) -> String

转为 vN 字符串（如 v1、v2）
