Struct r2d2_oracle::OracleConnectionManager [−][src]
An r2d2::ManageConnection
for oracle::Connection
s.
Example
use std::thread; use r2d2_oracle::OracleConnectionManager; let manager = OracleConnectionManager::new("user", "password", "localhost"); let pool = r2d2::Pool::builder() .max_size(15) .build(manager) .unwrap(); for _ in 0..20 { let pool = pool.clone(); thread::spawn(move || { let conn = pool.get().unwrap(); // use the connection // it will be returned to the pool when it falls out of scope. }); }
Implementations
impl OracleConnectionManager
[src]
pub fn new(
username: &str,
password: &str,
connect_string: &str
) -> OracleConnectionManager
[src]
username: &str,
password: &str,
connect_string: &str
) -> OracleConnectionManager
Initialise the connection manager with the data needed to create new connections.
Refer to the documentation of oracle::Connection
for further details on the parameters.
Example
let manager = OracleConnectionManager::new("user", "password", "localhost");
pub fn from_connector(connector: Connector) -> OracleConnectionManager
[src]
Initialise the connection manager with the data needed to create new connections using oracle::Connector
.
This allows setting additional connection data.
If a connection can be established only with a username, password and connect string, use new
instead.
Example
// connect system/manager as sysdba let mut connector = oracle::Connector::new("system", "manager", ""); connector.privilege(oracle::Privilege::Sysdba); let manager = OracleConnectionManager::from_connector(connector);
