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. pgxpool.ParseConfig parses PostgreSQL connection URI parameters including pool_max_conns, pool_min_conns, pool_max_conn_lifetime, pool_max_conn_idle_time, and pool_health_check_period into a pgxpool.Config.
  2. pgxpool.NewWithConfig initializes and returns a *pgxpool.Pool configured with connection settings, pool bounds, and lifecycle hook callbacks.
  3. pgxpool.Pool.Config returns the active *pgxpool.Config reflecting configured MaxConns, MinConns, ConnConfig, and pool lifetimes.
  4. pgxpool.Pool.Stat returns initial pool statistics including TotalConns, IdleConns, and MaxConns matching configuration.
  5. pgxpool.Config.Copy creates an independent copy of pool configuration where modifications do not mutate the source config.
  6. pgxpool.ParseConfig returns an error when given a malformed connection URI string.
  7. pgxpool.NewWithConfig panics when invoked with a nil config pointer.
