Struct PooledConnection 

Source 
pub struct PooledConnection { /* private fields */ }
Expand description

连接池中的连接条目，记录创建时间和最后使用时间

  • created_at：连接的原始创建时间，不随 acquire/release 重置， 用于 max_lifetime 过期判定。
  • last_used_at：上次归还到池的时间，用于 idle_timeout 空闲超时判定。

Implementations§

Source§

impl PooledConnection

Source

pub fn created_at(&self) -> Instant

连接的原始创建时间（不随 acquire/release 重置）

Source

pub fn into_inner(self) -> Box<dyn Connection>

提取内部连接（消费 PooledConnection）

用于将连接传递给 Transaction::new 等消费连接的 API。 调用此方法后，连接不再属于池，调用方需自行管理其生命周期。

Trait Implementations§

impl DerefMut for PooledConnection

Source§

fn deref_mut(&mut self) -> &mut Self::Target
