Implementations

impl FtpConnectionPool

pub fn new(max_connections: usize) -> Self

Create a new connection pool with default configuration

pub fn with_config(config: PoolConfig) -> Self

Create a new connection pool with custom configuration

pub async fn get_connection( &self, host: &str, port: u16, username: &str, password: &str, mode: FtpMode, ) -> Result<PooledConnection>

4. If pool is full, evict the least recently used connection

pub async fn return_connection(&self, conn: PooledConnection)

Return a connection to the pool for reuse

pub async fn cleanup_stale(&self)

Clean up stale connections

pub async fn stats(&self) -> PoolStats

Get pool statistics

pub async fn size(&self) -> usize

Get current pool size

pub async fn clear(&self)

Clear all connections from the pool

pub async fn has_connection( &self, host: &str, port: u16, username: &str, ) -> bool

Check if the pool has a connection for the given key
