Struct LayerStack 

Source 
pub struct LayerStack<S> { /* private fields */ }
Expand description

A stack for managing and applying middleware layers to a router.

LayerStack provides a way to accumulate layers and apply them to a router in the order they were added. Layers are applied via the push() method during configuration, and then applied to the router via apply() during the build phase.

Implementations§

Source§

impl<S> LayerStack<S>
where S: Clone + Send + Sync + 'static,

Source

pub fn new() -> LayerStack<S>

Source

pub fn push<L>(&mut self, layer: L)
where L: Layer<Route> + Clone + Send + Sync + 'static, <L as Layer<Route>>::Service: Service<Request<Body>> + Clone + Send + Sync + 'static, <<L as Layer<Route>>::Service as Service<Request<Body>>>::Response: IntoResponse + 'static, <<L as Layer<Route>>::Service as Service<Request<Body>>>::Error: Into<Infallible> + 'static, <<L as Layer<Route>>::Service as Service<Request<Body>>>::Future: Send + 'static,

Add a layer to the stack.

Layers are applied in FIFO order when apply() is called. Each layer will wrap the router after all controllers have been registered.

Source

pub fn apply(&self, router: Router<S>) -> Router<S>

Apply all layers to the given router.

Layers are applied in FIFO order (first pushed = first applied = outermost).
