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. Cursor.First and Cursor.Last navigate to the first and last key-value pairs in a bucket
  2. Cursor.Next and Cursor.Prev traverse key-value pairs sequentially in ascending and descending order
  3. Cursor.Seek positions at the first key greater than or equal to a target key
  4. Cursor.Delete removes current key-value pair in a writable transaction and returns ErrTxNotWritable in a read-only transaction
  5. Cursor.Bucket returns the parent bucket being traversed
