Struct mysql_async::PoolOptions

pub struct PoolOptions { /* fields omitted */ }

Connection pool options.

Methods

impl PoolOptions

pub const fn new(
    constraints: PoolConstraints,
    inactive_connection_ttl: Duration,
    ttl_check_interval: Duration
) -> Self

Creates PoolOptions.

pub const fn with_constraints(constraints: PoolConstraints) -> Self

Creates default PoolOptions with given constraints.

pub fn set_constraints(&mut self, constraints: PoolConstraints)

Sets pool constraints.

pub fn constraints(&self) -> PoolConstraints

Returns constrains value.

pub fn set_inactive_connection_ttl(&mut self, ttl: Duration)

Pool will recycle inactive connection if it outside of the lower bound of a pool and if it is idling longer than this value (defaults to DEFAULT_INACTIVE_CONNECTION_TTL).

Note that it may, actually, idle longer because of PoolOptions::ttl_check_interval.

pub fn inactive_connection_ttl(&self) -> Duration

Returns inactive_connection_ttl value.

pub fn set_ttl_check_interval(&mut self, interval: Duration)

Pool will check idling connection for expiration with this interval (defaults to DEFAULT_TTL_CHECK_INTERVAL).

If interval is less than one second, then DEFAULT_TTL_CHECK_INTERVAL will be used.

pub fn ttl_check_interval(&self) -> Duration

Returns ttl_check_interval value.
