Struct ConnectionPool 

pub struct ConnectionPool { /* private fields */ }

A pool of database connections.

Connections are recycled via an unbounded mpsc channel. When a PooledConnection is dropped, its inner Arc<Connection> is sent back through the channel so subsequent get() calls can reuse it instead of opening a new connection.

Implementations

impl ConnectionPool

pub async fn new(config: PoolConfig) -> Result<Self, ClientError>

Create a new connection pool.

pub async fn with_connection_config( config: PoolConfig, connection_config: ConnectionConfig, ) -> Result<Self, ClientError>

Create a pool with specific connection configuration.

pub async fn get(&self) -> Result<PooledConnection, ClientError>

Get a connection from the pool.

pub async fn return_connection(&self, conn: Arc<Connection>)

Return a connection to the pool (explicit async path).

pub async fn is_healthy(&self) -> bool

Check if the pool is healthy.

pub fn stats(&self) -> PoolStats

Get pool statistics.

pub async fn close(&self)

Close all connections in the pool.

pub fn size(&self) -> usize

Get the current pool size.

pub fn available(&self) -> usize
