Struct Router

#[non_exhaustive]
pub struct Router {
    pub routers: Vec<Router>,
    pub filters: Vec<Box<dyn Filter>>,
    pub hoops: Vec<Arc<dyn Handler>>,
    pub goal: Option<Arc<dyn Handler>>,
    /* private fields */
}

Route request to different handlers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

routers: Vec<Router>

The children of current router.

filters: Vec<Box<dyn Filter>>

The filters of current router.

hoops: Vec<Arc<dyn Handler>>

The middlewares of current router.

goal: Option<Arc<dyn Handler>>

The final handler to handle request of current router.
