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 a one hour sleep under a paused clock advances tokio::time::Instant by exactly one hour
- assert that hour of virtual time costs under 250 milliseconds of real time
- assert timeout on a future that never completes returns Err(Elapsed) whose Display is "deadline has elapsed"
- assert the clock stops exactly on the timeout deadline rather than somewhere past it
- assert a fresh Interval already has one tick due before anything awaits it
- assert taking that first tick costs zero virtual time
- assert advance() past five periods makes five ticks due at once under the default MissedTickBehavior::Burst
- assert the clock sits exactly 300 virtual seconds on from the interval's creation after that advance
- assert four ticks of a 60 second interval take 180 seconds of virtual time, not 240
- assert select! with a timeout branch picks the timeout when the other branch can never resolve
- assert the clock lands exactly on that select! timeout deadline
- assert two select! branches one millisecond apart resolve to the shorter one 100 times in a row
- assert those 100 races cost exactly one second of virtual time in total
- assert the whole run adds up to exactly 4116 seconds of virtual time
- assert 4116 seconds of virtual time pass in under a second of real time
- assert start_paused without enable_time still builds, then panics on the first sleep with the message naming enable_time
- assert a Sleep constructed outside the runtime instead panics that no reactor is running, even when that runtime has its time driver enabled
- assert start_paused on a multi_thread runtime panics inside build() with the message naming the current_thread runtime, instead of returning Err
