pub struct HandlerRefRef<'a> {
pub controller: &'a str,
pub action: &'a str,
}Expand description
Handler 引用(零拷贝借用版本)
与 HandlerRef 语义完全一致,但使用 &'a str 切片而非 String,
解析时零堆分配。适用于热路径(路由匹配)中临时解析 handler 字符串。
§用法
ⓘ
use sz_rust_router_facade::routing::HandlerRefRef;
let h = HandlerRefRef::parse("User@list").unwrap();
assert_eq!(h.controller, "User");
assert_eq!(h.action, "list");
// 转为 owned 版本(1 次分配)
let owned: HandlerRef = h.to_owned();Fields§
§controller: &'a str控制器名(首字母大写,如 User)
action: &'a str操作名(小驼峰,如 list / index)
Implementations§
Source§impl<'a> HandlerRefRef<'a>
impl<'a> HandlerRefRef<'a>
Sourcepub fn parse(s: &'a str) -> Result<HandlerRefRef<'a>, RouteConfigError>
pub fn parse(s: &'a str) -> Result<HandlerRefRef<'a>, RouteConfigError>
从 "Controller@action" 或 "Controller/action" 字符串解析(零分配)
使用 split_once 返回 &str 切片,不调用 to_string()。
校验规则与 HandlerRef::parse 完全一致。
Sourcepub fn to_owned(&self) -> HandlerRef
pub fn to_owned(&self) -> HandlerRef
转为 owned 版本(1 次分配)
Sourcepub fn to_handler_string(&self) -> String
pub fn to_handler_string(&self) -> String
转换为 "Controller@action" 字符串
