Struct PooledConn 

pub struct PooledConn<'a> { /* private fields */ }

A connection handle from the pool.

Important

• Does NOT hold the pool lock during I/O operations
• Only the connection’s own mutex is held during queries
• Multiple PooledConn instances can share the same underlying connection (VoltDB supports concurrent requests via handle-based tracking)

Implementations

impl PooledConn<'_>

pub fn query(&mut self, sql: &str) -> Result<VoltTable, VoltError>

Execute a SQL query.

pub fn list_procedures(&mut self) -> Result<VoltTable, VoltError>

List all stored procedures.

pub fn call_sp( &mut self, proc: &str, params: Vec<&dyn Value>, ) -> Result<VoltTable, VoltError>

Call a stored procedure with parameters.

pub fn upload_jar(&mut self, bs: Vec<u8>) -> Result<VoltTable, VoltError>

Upload a JAR file.

pub fn slot_index(&self) -> usize

Get the slot index of this connection (for debugging).
