Struct mobc_reql::Pool [−][src]
pub struct Pool<M>(_)
where
M: Manager;
A generic connection pool.
Implementations
impl<M> Pool<M> where
M: Manager,
[src]
impl<M> Pool<M> where
M: Manager,
[src]pub async fn set_max_open_conns(&'_ self, n: u64)
[src]
pub async fn set_max_open_conns(&'_ self, n: u64)
[src]Sets the maximum number of connections managed by the pool.
0 means unlimited, defaults to 10.
pub async fn set_max_idle_conns(&'_ self, n: u64)
[src]
pub async fn set_max_idle_conns(&'_ self, n: u64)
[src]Sets the maximum idle connection count maintained by the pool.
The pool will maintain at most this many idle connections
at all times, while respecting the value of max_open
.
Defaults to 2.
pub async fn set_conn_max_lifetime(&'_ self, max_lifetime: Option<Duration>)
[src]
pub async fn set_conn_max_lifetime(&'_ self, max_lifetime: Option<Duration>)
[src]Sets the maximum lifetime of connections in the pool.
Expired connections may be closed lazily before reuse.
None meas reuse forever. Defaults to None.
Panics
Panics if max_lifetime
is the zero Duration
.
pub async fn get(
&'_ self
) -> Result<Connection<M>, Error<<M as Manager>::Error>>
[src]
pub async fn get(
&'_ self
) -> Result<Connection<M>, Error<<M as Manager>::Error>>
[src]Returns a single connection by either opening a new connection or returning an existing connection from the connection pool. Conn will block until either a connection is returned or timeout.
pub async fn get_timeout(
&'_ self,
duration: Duration
) -> Result<Connection<M>, Error<<M as Manager>::Error>>
[src]
pub async fn get_timeout(
&'_ self,
duration: Duration
) -> Result<Connection<M>, Error<<M as Manager>::Error>>
[src]Retrieves a connection from the pool, waiting for at most timeout
The given timeout will be used instead of the configured connection timeout.
