Sample

destroy a stream cleanly and handle error listeners

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. assert destroy returns the passed stream instance
  2. assert destroy marks readable stream as destroyed
  3. assert destroy marks writable stream as destroyed
  4. assert destroy handles transform streams including zlib gzip
  5. assert destroy with suppress true removes error listeners and attaches a noop handler preventing unhandled error exceptions
  6. assert destroy without suppress preserves existing error listeners
  7. assert destroy safely returns non-stream objects and primitives without throwing
  8. assert destroy invokes custom destroy method on stream-like objects
