pub struct DefaultLobPrefetchSize;
Expand description

A type parameter for Connection::oci_attr and Connection::set_oci_attr to get and set OCI_ATTR_DEFAULT_LOBPREFETCH_SIZE, which specifies the default prefetch buffer size for each LOB locator

Examples

use oracle::oci_attr::DefaultLobPrefetchSize;

let lob_size = 64 * 1024;
conn.set_oci_attr::<DefaultLobPrefetchSize>(&lob_size)?;

let mut stmt = conn
    .statement("select CLOBCol from TestCLOBs where IntCol = :1")
    .lob_locator()
    .build()?;
let lob = stmt.query_row_as::<Clob>(&[&1])?;
