Implementations

impl PreparedStatement

pub fn new( idx: u64, param_oids: Vec<Oid>, row_desc_payload: Option<Vec<u8>>, wire_name: String, ) -> Self

Returns None if the statement doesn’t return rows.

pub fn row_desc_payload(&self) -> Option<&[u8]>

Get the raw RowDescription payload.

Returns None if the statement doesn’t return rows.
