Function execute_prepared 

pub fn execute_prepared(
    connection: &Arc<Mutex<RawConnection<SyncStream>>>,
    statement: &PreparedStatement,
    params: &[Option<&[u8]>],
) -> Result<Vec<Row>>

Executes a prepared statement with parameters, collecting all rows.

Every parameter is bound as PostgreSQL binary. Values whose ParamFormat is ParamFormat::Text — a scaled NUMERIC, a geography — will be rejected by the server, because the bytes ToSqlParam::encode_param produced for them are text. That combination is unreachable from hyperdb-api, which streams through RawConnection::start_execute_prepared_with_formats instead; if you are calling this directly and need mixed formats, use execute_prepared_no_result_with_formats or the streaming path.

Errors

• Returns Error (connection) if the connection mutex is poisoned.
• Returns Error (server) if the server rejects Bind / Execute (parameter type mismatch, constraint violation, etc.).
• Returns Error (I/O) / Error (closed) on wire-protocol I/O failure.
• Propagates row-construction errors from Row::new if a DataRow cannot be decoded against the prepared columns.
