Source§

impl Pool

Source

pub fn builder<C>(cfg: C) -> PoolBuilder
where Config: TryFrom<C>, Error: From<<Config as TryFrom<C>>::Error>,

Source

pub async fn get(&self) -> Result<PoolConnection<'_>, Error>

try to get a connection from pool. when pool is empty it will try to spawn new connection to database and if the process failed the outcome will return as Error
