Required Methods

fn connection_pool_max_size(&self) -> usize

Maximum number of connections allowed in a pool.

fn connection_pool_max_wait(&self) -> Option<Duration>

The maximum time to wait to obtain a connection, if any.

fn connection_pool_ttl(&self) -> Duration

Minimum TTL of a connection. It is expected that connections are routinely culled to balance load to the backing store.

fn connection_pool_ttl_stagger(&self) -> Duration

Minimum time between TTLing connections. Helps stagger reconnections to avoid stampeding the backing store.

fn connect_timeout(&self) -> Duration

Time to wait for a connection to be made before retrying.

fn tcp_user_timeout(&self) -> Duration

TCP user timeout for connections.

fn keepalives_idle(&self) -> Duration

Amount of idle time before a TCP keepalive packet is sent on a connection.

fn keepalives_interval(&self) -> Duration

Time interval between TCP keepalive probes.

fn keepalives_retries(&self) -> u32

Maximum number of TCP keepalive probes that will be sent before dropping a connection.
