Struct SerialPlugin

pub struct SerialPlugin { /* private fields */ }
Expand description

单号生成器插件

遵循 TaskPlugin 模式——插件是薄封装,不持有任何数据库连接或 SQL。 持久化逻辑通过 Arc<dyn SerialGenerator> 委托给业务方。

§自动配置模式

若未通过 new() 传入自定义生成器,插件在 start() 时自动创建 Memory 后端。 对于 Redis/PG 后端,需通过 new(serial_config, arc_generator) 注入。

Implementations§

Source§

impl SerialPlugin

Source

pub fn new(config: SerialConfig, generator: Arc<dyn SerialGenerator>) -> Self

使用自定义生成器创建插件(推荐——遵循 TaskPlugin 模式)

§示例
let backend = Arc::new(RedisSerialBackend::new(redis_conn));
let plugin = SerialPlugin::new(cfg.plugins.serial, backend);
Source

pub fn with_memory(config: SerialConfig) -> Self

使用默认 memory 后端创建插件(零依赖自动配置)

Source

pub fn generator(&self) -> Arc<dyn SerialGenerator>

获取生成器引用

§Panics

插件未启动时调用会 panic。
