This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. uvloop.EventLoopPolicy implements asyncio.AbstractEventLoopPolicy and creates uvloop.Loop instances
  2. uvloop.install sets uvloop.EventLoopPolicy as the default asyncio event loop policy
  3. uvloop.new_event_loop returns a new unclosed uvloop.Loop instance
  4. uvloop.run executes an async coroutine to completion and returns its result
  5. uvloop.run propagates unhandled exceptions raised inside the coroutine
  6. uvloop.run raises TypeError when passed a non-coroutine object
