Module handler 

The handler abstraction: extract parameters, produce a response, and combine them.

This module defines how a handler receives a Bundle (via FromRequest), produces a response (via IntoResponse), and how responses are combined across the handler chain (Call). It also provides the three handler wrappers: tower_handler::TowerHandler, async_handler::AsyncHandler, and sync_handler::SyncHandler.

Modules

async_handler

A type-erased asynchronous handler.

sync_handler

A type-erased synchronous handler.

tower_handler

A handler wrapper that integrates with the tower ecosystem.

Structs

Bundle

The container passed through the handler chain, carrying the request, response, state, and a stop flag.

State

The type-erased state carried through the handler chain.

StopFlag

A flag that stops the handler chain.

Traits

Call

A type-erased handler callable with a whole bundle.

FromRequest

Define how A value be extracted from a Bundle.

Handler

A handler that takes extracted parameters and returns a future yielding a response.

IntoResponse

A value that can be converted into a response.
