FieldData¶
Open result type for decoded column values. All built-in types (Bool,
I16, I32, I64, F32, F64, String, PgArray, PgComposite,
PgDate, PgTime, PgTimestamp, PgInterval, Bytea) conform
structurally via Stringable.
Custom codecs return their own types implementing this interface.
The encode path (FieldDataTypes) remains a closed union because parameters
must map to known PostgreSQL OIDs for the wire protocol. The decode path is
open because result values just need to be readable.
