Struct PoolConnection 

pub struct PoolConnection { /* private fields */ }

A connection borrowed from the pool.

Uses std::sync::Mutex for interior mutability because the driver’s PoolGuard requires &mut self for queries, but the Executor trait takes &self. The mutex is uncontended in practice — a single connection is used by one caller at a time, never shared between concurrent callers.

Returned to the pool when dropped.
