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. pgx.BeginFunc initiates transaction on db, calls callback function, and commits upon successful return
  2. pgx.BeginFunc rolls back transaction and propagates error when callback function returns error
  3. pgx.BeginFunc returns db.Begin error immediately without invoking callback when transaction start fails
  4. pgx.BeginFunc returns commit error when callback succeeds but transaction commit fails
  5. pgx.BeginTxFunc passes configured TxOptions to db.BeginTx and commits transaction upon callback completion
  6. pgx.BeginTxFunc rolls back transaction and propagates error when callback fails with TxOptions configured
  7. sample helpers WithTransaction, WithTransactionOptions, WithReadonlyTransaction, and WithSerializableTransaction provide convenient transactional execution wrappers
