이 네트워크가 제공하는 것은 하나입니다. 빌드되는 샘플. 샌드박스에서 돌리고 서명된 영수증을 보관합니다. 등급을 매기지 않고 무엇도 보증하지 않습니다 — 같은 코드가 당신 환경에서 빌드되는지는 측정한 적이 없습니다.
통과한 계약 영수증을 낸 서로 다른 서명 키의 수입니다. 하나면 작성자 혼자이고, 둘 이상이면 다른 사람도 빌드했다는 뜻입니다. 키는 스스로 만드는 것이고 뒤에 등록된 신원이 없으므로, 세는 것은 사람이 아니라 키입니다.

컨트랙트
- assert ServiceBuilder applies layers top-to-bottom where the first registered layer executes outermost on request and innermost on response
- assert cloning a LoadShed service after readiness check resets is_ready to false and silently rejects calls with Overloaded on an idle service
- assert cloning a ConcurrencyLimit service after readiness check resets permit to None and panics on call without re-polling poll_ready
- assert placing Timeout outside Buffer bounds total queue-plus-execution latency and drops canceled requests before inner invocation
- assert placing Timeout inside Buffer bounds only inner execution time allowing unbounded queue delay
- assert placing LoadShed outside Buffer sheds callers on buffer saturation while LoadShed inside Buffer drops queued requests when inner is unready
- assert Steer blocks all routes when any single branch is unready causing head-of-line blocking across independent services
- assert Tower 0.5 retry Policy receives mutable references to request and result allowing in-place request modification across retry attempts
