Häufige Annahme

Stack::new(a, b) establishes a middleware pipeline where layer a executes before layer b on incoming requests, matching left-to-right argument order and tuple composition

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• Stack::new(layer_a, layer_b).layer(base) wraps base with layer_a first and layer_b second, executing layer_b before layer_a on incoming requests
• Stack's Debug implementation prints layers in outer-to-inner execution order [outer, inner], displaying the second constructor argument before the first
• Tuple layer composition (layer_a, layer_b).layer(base) executes layer_a before layer_b on incoming requests, the reverse of Stack::new positional ordering
• Stack::new(Identity::new(), layer_a) applies layer_a directly around the base service without altering request execution
