[−][src]Struct mpool::Builder
A builder for a connection pool.
Fields
max_lifetime: Option<Duration>
idle_timeout: Option<Duration>
connection_timeout: Option<Duration>
max_size: u32
check_interval: Option<Duration>
Methods
impl<M> Builder<M> where
M: ManageConnection,
[src]
M: ManageConnection,
pub fn new() -> Self
[src]
Parameters are initialized with their default values.
pub fn max_lifetime(self, max_lifetime: Option<Duration>) -> Self
[src]
Sets the maximum lifetime of connections in the pool.
If a connection reaches its maximum lifetime while checked out it will be closed when it is returned to the pool.
Defaults to 30 minutes.
use default if max_lifetime
is the zero Duration
.
pub fn idle_timeout(self, idle_timeout: Option<Duration>) -> Self
[src]
Sets the idle timeout used by the pool.
If set, connections will be closed after exceed idle time.
Defaults to 3 minutes.
use default if idle_timeout
is the zero Duration
.
pub fn connection_timeout(self, connection_timeout: Option<Duration>) -> Self
[src]
Sets the connection timeout used by the pool.
Calls to Pool::get
will wait this long for a connection to become
available before returning an error.
Defaults to 3 seconds.
don't timeout if connection_timeout
is the zero duration
pub fn max_size(self, max_size: u32) -> Self
[src]
Sets the maximum number of connections managed by the pool.
Defaults to 10.
no limited if max_size
is 0.
pub fn check_interval(self, interval: Option<Duration>) -> Self
[src]
Sets the check interval of connections managed by the pool use the ManageConnection::check
.
Defaults to 3s.
pub fn build(&self, manager: M) -> Pool<M> where
M: ManageConnection,
[src]
M: ManageConnection,
Consumes the builder, returning a new, initialized pool.
