pub enum Lifetime {
Singleton,
Transient,
Scoped,
}Expand description
服务生命周期
对齐 PHP app()->bind()(瞬态)、app()->singleton()(单例)、
app()->scoped()(请求作用域)三种语义。
Variants§
Singleton
单例:整个应用生命周期内只创建一次,后续 make 返回同一实例
Transient
瞬态:每次 make 都调用工厂创建新实例
Scoped
请求作用域:同一 ScopeId 内单例,不同 ScopeId 各自独立实例
对齐 PHP app()->scoped()。在 Rust 中,ScopeId 通常由 Web 框架
在请求开始时生成(如 axum 中间件生成 UUID 的低 64 位),请求结束时
调用 Container::clear_scope 清理。
