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. pgtype.Present is a Status constant with value 2 representing non-null present state
  2. Setting non-nil values on pgtype types transitions Status to Present
  3. Get returns the underlying value for Present status, nil for Null status, and Status for Undefined
  4. AssignTo copies the underlying value to destination pointers when Status is Present
  5. Value implements driver.Valuer returning value representation for Present status and nil for Null
  6. Scan implements sql.Scanner setting Status to Present for non-nil values and Null for nil
  7. EncodeText and DecodeText encode and decode textual data when Status is Present
  8. EncodeBinary and DecodeBinary encode and decode binary format when Status is Present
