Struct PoolRef

Source 
pub struct PoolRef<'a, M: Manager> { /* private fields */ }

Implementations§

Source§

impl<M: Manager> PoolRef<'_, M>

Source

pub fn get_conn(&mut self) -> &mut M::Connection

get a mut reference of connection.

Source

pub fn take_conn(&mut self) -> Option<M::Connection>

take the the ownership of connection from pool and it won’t be pushed back to pool anymore.

Source

pub fn push_conn(&mut self, conn: M::Connection)

manually push a connection to pool. We treat this connection as a new born one.

operation will fail if the pool is already in full capacity(no error will return and this connection will be dropped silently)

Source

pub fn get_manager(&self) -> &M
