Struct BoxedHandler 

pub struct BoxedHandler { /* private fields */ }

Type-erased handler for storing in collections.

While Handler uses associated types for zero-cost abstraction, we need type erasure to store different handlers in the same Vec.

This type performs the erasure while keeping the actual handler call as optimized as possible via vtable dispatch with inlined inner handlers.

Implementations

impl BoxedHandler

pub fn new<H: Handler>(handler: H) -> Self

Create a new boxed handler from any Handler.

The handler is wrapped in an Arc for cheap cloning.

pub fn call( &self, req: HttpRequest, ) -> Pin<Box<dyn Future<Output = Result<HttpResponse, Error>> + Send>>

Call the handler.

This goes through a vtable but the actual handler implementation is monomorphized and can be inlined within the wrapper.

Trait Implementations

impl Clone for BoxedHandler

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
